    descriptionThe SUSE Linux Enterprise 11 SP4 kernel was updated to receive various security and bugfixes. This update adds mitigations for various side channel attacks against modern CPUs that could disclose content of otherwise unreadable memory (bnc#1068032). - CVE-2017-5753: Local attackers on systems with modern CPUs featuring deep instruction pipelining could use attacker controllable speculative execution over code patterns in the Linux Kernel to leak content from otherwise not readable memory in the same address space, allowing retrieval of passwords, cryptographic keys and other secrets. This problem is mitigated by adding speculative fencing on affected code paths throughout the Linux kernel. This issue is addressed for the x86_64, the IBM Power and IBM zSeries architecture. - CVE-2017-5715: Local attackers on systems with modern CPUs featuring branch prediction could use mispredicted branches to speculatively execute code patterns that in turn could be made to leak other non-readable content in the same address space, an attack similar to CVE-2017-5753. This problem is mitigated by disabling predictive branches, depending on CPU architecture either by firmware updates and/or fixes in the user-kernel privilege boundaries. This is done with help of Linux Kernel fixes on the Intel/AMD x86_64 and IBM zSeries architectures. On x86_64, this requires also updates of the CPU microcode packages, delivered in separate updates. For IBM Power and zSeries the required firmware updates are supplied over regular channels by IBM. As this feature can have a performance impact, it can be disabled using the

"The SUSE Linux Enterprise 11 SP4 kernel was updated to receive various
security and bugfixes. This update adds mitigations for various side
channel attacks against modern CPUs that could disclose content of
otherwise unreadable memory (bnc#1068032).

  - CVE-2017-5753: Local attackers on systems with modern
    CPUs featuring deep instruction pipelining could use
    attacker controllable speculative execution over code
    patterns in the Linux Kernel to leak content from
    otherwise not readable memory in the same address space,
    allowing retrieval of passwords, cryptographic keys and
    other secrets. This problem is mitigated by adding
    speculative fencing on affected code paths throughout
    the Linux kernel. This issue is addressed for the
    x86_64, the IBM Power and IBM zSeries architecture.

  - CVE-2017-5715: Local attackers on systems with modern
    CPUs featuring branch prediction could use mispredicted
    branches to speculatively execute code patterns that in
    turn could be made to leak other non-readable content in
    the same address space, an attack similar to
    CVE-2017-5753. This problem is mitigated by disabling
    predictive branches, depending on CPU architecture
    either by firmware updates and/or fixes in the
    user-kernel privilege boundaries. This is done with help
    of Linux Kernel fixes on the Intel/AMD x86_64 and IBM
    zSeries architectures. On x86_64, this requires also
    updates of the CPU microcode packages, delivered in
    separate updates. For IBM Power and zSeries the required
    firmware updates are supplied over regular channels by
    IBM. As this feature can have a performance impact, it
    can be disabled using the 'nospec' kernel commandline
    option.

  - CVE-2017-5754: Local attackers on systems with modern
    CPUs featuring deep instruction pipelining could use
    code patterns in userspace to speculative executive code
    that would read otherwise read protected memory, an
    attack similar to CVE-2017-5753. This problem is
    mitigated by unmapping the Linux Kernel from the user
    address space during user code execution, following a
    approach called 'KAISER'. The terms used here are
    'KAISER' / 'Kernel Address Isolation' and 'PTI' / 'Page
    Table Isolation'. This update does this on the Intel
    x86_64 and IBM Power architecture. Updates are also
    necessary for the ARM architecture, but will be
    delivered in the next round of updates. This feature can
    be enabled / disabled by the 'pti=[on|off|auto]' or
    'nopti' commandline options. The following security bugs
    were fixed :

  - CVE-2017-17806: The HMAC implementation (crypto/hmac.c)
    in the Linux kernel did not validate that the underlying
    cryptographic hash algorithm is unkeyed, allowing a
    local attacker able to use the AF_ALG-based hash
    interface (CONFIG_CRYPTO_USER_API_HASH) and the SHA-3
    hash algorithm (CONFIG_CRYPTO_SHA3) to cause a kernel
    stack-based buffer overflow by executing a crafted
    sequence of system calls that encounter a missing SHA-3
    initialization (bnc#1073874).

  - CVE-2017-17805: The Salsa20 encryption algorithm in the
    Linux kernel did not correctly handle zero-length
    inputs, allowing a local attacker able to use the
    AF_ALG-based skcipher interface
    (CONFIG_CRYPTO_USER_API_SKCIPHER) to cause a denial of
    service (uninitialized-memory free and kernel crash) or
    have unspecified other impact by executing a crafted
    sequence of system calls that use the blkcipher_walk
    API. Both the generic implementation
    (crypto/salsa20_generic.c) and x86 implementation
    (arch/x86/crypto/salsa20_glue.c) of Salsa20 were
    vulnerable (bnc#1073792).

  - CVE-2017-15868: The bnep_add_connection function in
    net/bluetooth/bnep/core.c in the Linux kernel did not
    ensure that an l2cap socket is available, which allowed
    local users to gain privileges via a crafted application
    (bnc#1071470).

  - CVE-2017-13167: An elevation of privilege vulnerability
    in the kernel sound timer. (bnc#1072876).

  - CVE-2017-16538: drivers/media/usb/dvb-usb-v2/lmedm04.c
    in the Linux kernel allowed local users to cause a
    denial of service (general protection fault and system
    crash) or possibly have unspecified other impact via a
    crafted USB device, related to a missing warm-start
    check and incorrect attach timing
    (dm04_lme2510_frontend_attach versus dm04_lme2510_tuner)
    (bnc#1066569).

  - CVE-2017-17558: The usb_destroy_configuration function
    in drivers/usb/core/config.c in the USB core subsystem
    in the Linux kernel did not consider the maximum number
    of configurations and interfaces before attempting to
    release resources, which allowed local users to cause a
    denial of service (out-of-bounds write access) or
    possibly have unspecified other impact via a crafted USB
    device (bnc#1072561).

  - CVE-2017-17450: net/netfilter/xt_osf.c in the Linux
    kernel did not require the CAP_NET_ADMIN capability for
    add_callback and remove_callback operations, which
    allowed local users to bypass intended access
    restrictions because the xt_osf_fingers data structure
    is shared across all net namespaces (bnc#1071695).

  - CVE-2017-8824: The dccp_disconnect function in
    net/dccp/proto.c in the Linux kernel allowed local users
    to gain privileges or cause a denial of service
    (use-after-free) via an AF_UNSPEC connect system call
    during the DCCP_LISTEN state (bnc#1070771).

  - CVE-2017-16939: The XFRM dump policy implementation in
    net/xfrm/xfrm_user.c in the Linux kernel allowed local
    users to gain privileges or cause a denial of service
    (use-after-free) via a crafted SO_RCVBUF setsockopt
    system call in conjunction with XFRM_MSG_GETPOLICY
    Netlink messages (bnc#1069702).

  - CVE-2017-15115: The sctp_do_peeloff function in
    net/sctp/socket.c in the Linux kernel did not check
    whether the intended netns is used in a peel-off action,
    which allowed local users to cause a denial of service
    (use-after-free and system crash) or possibly have
    unspecified other impact via crafted system calls
    (bnc#1068671).

  - CVE-2017-14106: The tcp_disconnect function in
    net/ipv4/tcp.c in the Linux kernel allowed local users
    to cause a denial of service (__tcp_select_window
    divide-by-zero error and system crash) by triggering a
    disconnect within a certain tcp_recvmsg code path
    (bnc#1056982).

  - CVE-2017-11600: net/xfrm/xfrm_policy.c in the Linux
    kernel through 4.12.3, when CONFIG_XFRM_MIGRATE is
    enabled, did not ensure that the dir value of
    xfrm_userpolicy_id is XFRM_POLICY_MAX or less, which
    allowed local users to cause a denial of service
    (out-of-bounds access) or possibly have unspecified
    other impact via an XFRM_MSG_MIGRATE xfrm Netlink
    message (bnc#1050231).

  - CVE-2017-7472: The KEYS subsystem in the Linux kernel
    allowed local users to cause a denial of service (memory
    consumption) via a series of
    KEY_REQKEY_DEFL_THREAD_KEYRING keyctl_set_reqkey_keyring
    calls (bnc#1034862).

  - CVE-2017-16534: The cdc_parse_cdc_header function in
    drivers/usb/core/message.c in the Linux kernel allowed
    local users to cause a denial of service (out-of-bounds
    read and system crash) or possibly have unspecified
    other impact via a crafted USB device (bnc#1066693).

The update package also includes non-security fixes. See advisory for

    descriptionAccording to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - The XFRM dump policy implementation in net/xfrm/xfrm_user.c in the Linux kernel before 4.13.11 allows local users to gain privileges or cause a denial of service (use-after-free) via a crafted SO_RCVBUF setsockopt system call in conjunction with XFRM_MSG_GETPOLICY Netlink messages.(CVE-2017-16939) - The bio_map_user_iov and bio_unmap_user functions in block/bio.c in the Linux kernel before 4.13.8 do unbalanced refcounting when a SCSI I/O vector has small consecutive buffers belonging to the same page. The bio_add_pc_page function merges them into one, but the page reference is never dropped. This causes a memory leak and possible system lockup (exploitable against the host OS by a guest OS user, if a SCSI disk is passed through to a virtual machine) due to an out-of-memory condition.(CVE-2017-12190) - The assoc_array_insert_into_terminal_node function in lib/assoc_array.c in the Linux kernel before 4.13.11 mishandles node splitting, which allows local users to cause a denial of service (NULL pointer dereference and panic) via a crafted application, as demonstrated by the keyring key type, and key addition and link creation operations.(CVE-2017-12193) - The ip6_find_1stfragopt function in net/ipv6/output_core.c in the Linux kernel through 4.12.3 allows local users to cause a denial of service (integer overflow and infinite loop) by leveraging the ability to open a raw socket.(CVE-2017-7542) - The bnep_add_connection function in net/bluetooth/bnep/core.c in the Linux kernel before 3.19 does not ensure that an l2cap socket is available, which allows local users to gain privileges via a crafted application.(CVE-2017-15868) - The dccp_disconnect function in net/dccp/proto.c in the Linux kernel through 4.14.3 allows local users to gain privileges or cause a denial of service (use-after-free) via an AF_UNSPEC connect system call during the DCCP_LISTEN state.(CVE-2017-8824) - net/netfilter/nfnetlink_cthelper.c in the Linux kernel through 4.14.4 does not require the CAP_NET_ADMIN capability for new, get, and del operations, which allows local users to bypass intended access restrictions because the nfnl_cthelper_list data structure is shared across all net namespaces.(CVE-2017-17448) - The __netlink_deliver_tap_skb function in net/netlink/af_netlink.c in the Linux kernel through 4.14.4, when CONFIG_NLMON is enabled, does not restrict observations of Netlink messages to a single net namespace, which allows local users to obtain sensitive information by leveraging the CAP_NET_ADMIN capability to sniff an nlmon interface for all Netlink activity on the system.(CVE-2017-17449) - net/netfilter/xt_osf.c in the Linux kernel through 4.14.4 does not require the CAP_NET_ADMIN capability for add_callback and remove_callback operations, which allows local users to bypass intended access restrictions because the xt_osf_fingers data structure is shared across all net namespaces.(CVE-2017-17450) - The usb_destroy_configuration function in drivers/usb/core/config.c in the USB core subsystem in the Linux kernel through 4.14.5 does not consider the maximum number of configurations and interfaces before attempting to release resources, which allows local users to cause a denial of service (out-of-bounds write access) or possibly have unspecified other impact via a crafted USB device.(CVE-2017-17558) - The Salsa20 encryption algorithm in the Linux kernel before 4.14.8 does not correctly handle zero-length inputs, allowing a local attacker able to use the AF_ALG-based skcipher interface (CONFIG_CRYPTO_USER_API_SKCIPHER) to cause a denial of service (uninitialized-memory free and kernel crash) or have unspecified other impact by executing a crafted sequence of system calls that use the blkcipher_walk API. Both the generic implementation (crypto/salsa20_generic.c) and x86 implementation (arch/x86/crypto/salsa20_glue.c) of Salsa20 were vulnerable.(CVE-2017-17805) - The HMAC implementation (crypto/hmac.c) in the Linux kernel before 4.14.8 does not validate that the underlying cryptographic hash algorithm is unkeyed, allowing a local attacker able to use the AF_ALG-based hash interface (CONFIG_CRYPTO_USER_API_HASH) and the SHA-3 hash algorithm (CONFIG_CRYPTO_SHA3) to cause a kernel stack buffer overflow by executing a crafted sequence of system calls that encounter a missing SHA-3 initialization.(CVE-2017-17806) - he KEYS subsystem in the Linux kernel before 4.14.6 omitted an access-control check when adding a key to the current task

"According to the versions of the kernel packages installed, the
EulerOS installation on the remote host is affected by the following
vulnerabilities :

  - The XFRM dump policy implementation in
    net/xfrm/xfrm_user.c in the Linux kernel before 4.13.11
    allows local users to gain privileges or cause a denial
    of service (use-after-free) via a crafted SO_RCVBUF
    setsockopt system call in conjunction with
    XFRM_MSG_GETPOLICY Netlink messages.(CVE-2017-16939)

  - The bio_map_user_iov and bio_unmap_user functions in
    block/bio.c in the Linux kernel before 4.13.8 do
    unbalanced refcounting when a SCSI I/O vector has small
    consecutive buffers belonging to the same page. The

    the host OS by a guest OS user, if a SCSI disk is
    passed through to a virtual machine) due to an
    out-of-memory condition.(CVE-2017-12190)

  - The assoc_array_insert_into_terminal_node function in
    lib/assoc_array.c in the Linux kernel before 4.13.11
    mishandles node splitting, which allows local users to
    cause a denial of service (NULL pointer dereference and
    panic) via a crafted application, as demonstrated by
    the keyring key type, and key addition and link
    creation operations.(CVE-2017-12193)

  - The ip6_find_1stfragopt function in
    net/ipv6/output_core.c in the Linux kernel through
    4.12.3 allows local users to cause a denial of service
    (integer overflow and infinite loop) by leveraging the
    ability to open a raw socket.(CVE-2017-7542)

  - The bnep_add_connection function in
    net/bluetooth/bnep/core.c in the Linux kernel before
    3.19 does not ensure that an l2cap socket is available,
    which allows local users to gain privileges via a
    crafted application.(CVE-2017-15868)

  - The dccp_disconnect function in net/dccp/proto.c in the
    Linux kernel through 4.14.3 allows local users to gain
    privileges or cause a denial of service
    (use-after-free) via an AF_UNSPEC connect system call
    during the DCCP_LISTEN state.(CVE-2017-8824)

  - net/netfilter/nfnetlink_cthelper.c in the Linux kernel
    through 4.14.4 does not require the CAP_NET_ADMIN
    capability for new, get, and del operations, which
    allows local users to bypass intended access
    restrictions because the nfnl_cthelper_list data
    structure is shared across all net
    namespaces.(CVE-2017-17448)

  - The __netlink_deliver_tap_skb function in
    net/netlink/af_netlink.c in the Linux kernel through
    4.14.4, when CONFIG_NLMON is enabled, does not restrict
    observations of Netlink messages to a single net
    namespace, which allows local users to obtain sensitive
    information by leveraging the CAP_NET_ADMIN capability
    to sniff an nlmon interface for all Netlink activity on
    the system.(CVE-2017-17449)

  - net/netfilter/xt_osf.c in the Linux kernel through
    4.14.4 does not require the CAP_NET_ADMIN capability
    for add_callback and remove_callback operations, which
    allows local users to bypass intended access
    restrictions because the xt_osf_fingers data structure
    is shared across all net namespaces.(CVE-2017-17450)

  - The usb_destroy_configuration function in
    drivers/usb/core/config.c in the USB core subsystem in
    the Linux kernel through 4.14.5 does not consider the
    maximum number of configurations and interfaces before
    attempting to release resources, which allows local
    users to cause a denial of service (out-of-bounds write
    access) or possibly have unspecified other impact via a
    crafted USB device.(CVE-2017-17558)

  - The Salsa20 encryption algorithm in the Linux kernel
    before 4.14.8 does not correctly handle zero-length
    inputs, allowing a local attacker able to use the
    AF_ALG-based skcipher interface
    (CONFIG_CRYPTO_USER_API_SKCIPHER) to cause a denial of
    service (uninitialized-memory free and kernel crash) or
    have unspecified other impact by executing a crafted
    sequence of system calls that use the blkcipher_walk
    API. Both the generic implementation
    (crypto/salsa20_generic.c) and x86 implementation
    (arch/x86/crypto/salsa20_glue.c) of Salsa20 were
    vulnerable.(CVE-2017-17805)

  - The HMAC implementation (crypto/hmac.c) in the Linux
    kernel before 4.14.8 does not validate that the
    underlying cryptographic hash algorithm is unkeyed,
    allowing a local attacker able to use the AF_ALG-based
    hash interface (CONFIG_CRYPTO_USER_API_HASH) and the
    SHA-3 hash algorithm (CONFIG_CRYPTO_SHA3) to cause a
    kernel stack buffer overflow by executing a crafted
    sequence of system calls that encounter a missing SHA-3
    initialization.(CVE-2017-17806)

  - he KEYS subsystem in the Linux kernel before 4.14.6
    omitted an access-control check when adding a key to
    the current task's 'default request-key keyring' via
    the request_key() system call, allowing a local user to
    use a sequence of crafted system calls to add keys to a
    keyring with only Search permission (not Write
    permission) to that keyring, related to
    construct_get_dest_keyring() in
    security/keys/request_key.c.(CVE-2017-17807)

  - The Linux Kernel 2.6.32 and later are affected by a
    denial of service, by flooding the diagnostic port 0x80
    an exception can be triggered leading to a kernel
    panic.(CVE-2017-1000407)

    descriptionThe SUSE Linux Enterprise 11 SP3 LTSS kernel was updated to receive various security and bugfixes. This update adds mitigations for various side channel attacks against modern CPUs that could disclose content of otherwise unreadable memory (bnc#1068032). - CVE-2017-5753: Local attackers on systems with modern CPUs featuring deep instruction pipelining could use attacker controllable speculative execution over code patterns in the Linux Kernel to leak content from otherwise not readable memory in the same address space, allowing retrieval of passwords, cryptographic keys and other secrets. This problem is mitigated by adding speculative fencing on affected code paths throughout the Linux kernel. - CVE-2017-5715: Local attackers on systems with modern CPUs featuring branch prediction could use mispredicted branches to speculatively execute code patterns that in turn could be made to leak other non-readable content in the same address space, an attack similar to CVE-2017-5753. This problem is mitigated by disabling predictive branches, depending on CPU architecture either by firmware updates and/or fixes in the user-kernel privilege boundaries.

"The SUSE Linux Enterprise 11 SP3 LTSS kernel was updated to receive
various security and bugfixes. This update adds mitigations for
various side channel attacks against modern CPUs that could disclose
content of otherwise unreadable memory (bnc#1068032).

  - CVE-2017-5753: Local attackers on systems with modern
    CPUs featuring deep instruction pipelining could use
    attacker controllable speculative execution over code
    patterns in the Linux Kernel to leak content from
    otherwise not readable memory in the same address space,
    allowing retrieval of passwords, cryptographic keys and
    other secrets. This problem is mitigated by adding
    speculative fencing on affected code paths throughout
    the Linux kernel.

  - CVE-2017-5715: Local attackers on systems with modern
    CPUs featuring branch prediction could use mispredicted
    branches to speculatively execute code patterns that in
    turn could be made to leak other non-readable content in
    the same address space, an attack similar to
    CVE-2017-5753. This problem is mitigated by disabling
    predictive branches, depending on CPU architecture
    either by firmware updates and/or fixes in the
    user-kernel privilege boundaries. Please contact your
    CPU / hardware vendor for potential microcode or BIOS
    updates needed for this fix. As this feature can have a
    performance impact, it can be disabled using the
    'nospec' kernel commandline option.

  - CVE-2017-5754: Local attackers on systems with modern
    CPUs featuring deep instruction pipelining could use
    code patterns in userspace to speculative executive code
    that would read otherwise read protected memory, an
    attack similar to CVE-2017-5753. This problem is
    mitigated by unmapping the Linux Kernel from the user
    address space during user code execution, following a
    approach called 'KAISER'. The terms used here are
    'KAISER' / 'Kernel Address Isolation' and 'PTI' / 'Page
    Table Isolation'. This feature is disabled on unaffected
    architectures. This feature can be enabled / disabled by
    the 'pti=[on|off|auto]' or 'nopti' commandline options.
    The following security bugs were fixed :

  - CVE-2017-1000251: The native Bluetooth stack in the

    allowed local users to cause a denial of service
    (out-of-bounds access) or possibly have unspecified
    other impact via an XFRM_MSG_MIGRATE xfrm Netlink
    message (bnc#1050231).

  - CVE-2017-13080: Wi-Fi Protected Access (WPA and WPA2)
    allowed reinstallation of the Group Temporal Key (GTK)
    during the group key handshake, allowing an attacker

  - CVE-2017-17450: net/netfilter/xt_osf.c in the Linux
    kernel did not require the CAP_NET_ADMIN capability for
    add_callback and remove_callback operations, which
    allowed local users to bypass intended access
    restrictions because the xt_osf_fingers data structure
    is shared across all net namespaces (bnc#1071695
    1074033).

    vulnerable (bnc#1073792).

  - CVE-2017-17806: The HMAC implementation (crypto/hmac.c)
    in the Linux kernel did not validate that the underlying
    cryptographic hash algorithm is unkeyed, allowing a
    local attacker able to use the AF_ALG-based hash
    interface (CONFIG_CRYPTO_USER_API_HASH) and the SHA-3
    hash algorithm (CONFIG_CRYPTO_SHA3) to cause a kernel
    stack-based buffer overflow by executing a crafted
    sequence of system calls that encounter a missing SHA-3
    initialization (bnc#1073874).

  - CVE-2017-7472: The KEYS subsystem in the Linux kernel
    allowed local users to cause a denial of service (memory
    consumption) via a series of
    KEY_REQKEY_DEFL_THREAD_KEYRING keyctl_set_reqkey_keyring
    calls (bnc#1034862).

  - CVE-2017-8824: The dccp_disconnect function in
    net/dccp/proto.c in the Linux kernel allowed local users
    to gain privileges or cause a denial of service
    (use-after-free) via an AF_UNSPEC connect system call
    during the DCCP_LISTEN state (bnc#1070771).

(interface unavailability). (CVE-2018-1000026)

It was discovered that the Reliable Datagram Socket (RDS)
implementation in the Linux kernel contained an out-of-bounds during
RDMA page allocation. An attacker could use this to cause a denial of
service (system crash) or possibly execute arbitrary code.
(CVE-2018-5332)

Mohamed Ghannam discovered a NULL pointer dereference in the RDS
(Reliable Datagram Sockets) protocol implementation of the Linux
kernel. A local attacker could use this to cause a denial of service
(system crash). (CVE-2018-5333)

Fan Long Fei  discovered that a race condition existed in loop block
device implementation in the Linux kernel. A local attacker could use
this to cause a denial of service (system crash) or possibly execute
arbitrary code. (CVE-2018-5344).

"According to the version of the vzkernel package and the
readykernel-patch installed, the Virtuozzo installation on the remote
host is affected by the following vulnerabilities :

  - Linux kernel before version 4.16-rc7 is vulnerable to a
    null pointer dereference in dccp_write_xmit() function
    in net/dccp/output.c in that allows a local user to
    cause a denial of service by a number of certain
    crafted system calls.

  - It was found that _sctp_make_chunk() function did not
    check if the chunk length for INIT and INIT_ACK packets
    was within the allowed limits. A local attacker could
    exploit this to trigger a kernel crash.

  - It was discovered that nfnl_cthelper_list structure was
    accessible to any user with CAP_NET_ADMIN capability in
    a network namespace. An unprivileged local user could
    exploit that to affect netfilter conntrack helpers on
    the host.

  - It was discovered that a nlmon link inside a child
    network namespace was not restricted to that namespace.
    An unprivileged local user could exploit that to
    monitor system-wide netlink activity.

  - The KEYS subsystem in the Linux kernel omitted an
    access-control check when writing a key to the current
    task's default keyring, allowing a local user to bypass
    security checks to the keyring. This compromises the
    validity of the keyring for those who rely on it.

  - net/netfilter/xt_osf.c in the Linux kernel through
    4.14.4 does not require the CAP_NET_ADMIN capability
    for add_callback and remove_callback operations. This
    allows local users to bypass intended access
    restrictions because the xt_osf_fingers data structure
    is shared across all network namespaces.

    restrictions because the nfnl_cthelper_list data
    structure is shared across all net namespaces
    (bnc#1071693).

  - CVE-2017-17449: The __netlink_deliver_tap_skb function
    in net/netlink/af_netlink.c in the Linux kernel did not
    restrict observations of Netlink messages to a single
    net namespace, which allowed local users to obtain
    sensitive information by leveraging the CAP_NET_ADMIN
    capability to sniff an nlmon interface for all Netlink
    activity on the system (bnc#1071694).

  - CVE-2017-17450: net/netfilter/xt_osf.c in the Linux
    kernel did not require the CAP_NET_ADMIN capability for
    add_callback and remove_callback operations, which

    descriptionThe openSUSE Leap 42.2 kernel was updated to 4.4.102 to receive various security and bugfixes. The following security bugs were fixed : - CVE-2017-1000405: A bug in the THP CoW support could be used by local attackers to corrupt memory of other processes and cause them to crash (bnc#1069496). - CVE-2017-1000410: The Linux kernel was affected by an information leak in the processing of incoming L2CAP commands - ConfigRequest, and ConfigResponse messages. (bnc#1070535). - CVE-2017-11600: net/xfrm/xfrm_policy.c in the Linux kernel did not ensure that the dir value of xfrm_userpolicy_id is XFRM_POLICY_MAX or less, which allowed local users to cause a denial of service (out-of-bounds access) or possibly have unspecified other impact via an XFRM_MSG_MIGRATE xfrm Netlink message (bnc#1050231). - CVE-2017-12193: The assoc_array_insert_into_terminal_node function in lib/assoc_array.c in the Linux kernel mishandled node splitting, which allowed local users to cause a denial of service (NULL pointer dereference and panic) via a crafted application, as demonstrated by the keyring key type, and key addition and link creation operations (bnc#1066192). - CVE-2017-15115: The sctp_do_peeloff function in net/sctp/socket.c in the Linux kernel did not check whether the intended netns is used in a peel-off action, which allowed local users to cause a denial of service (use-after-free and system crash) or possibly have unspecified other impact via crafted system calls (bnc#1068671). - CVE-2017-16528: sound/core/seq_device.c in the Linux kernel allowed local users to cause a denial of service (snd_rawmidi_dev_seq_free use-after-free and system crash) or possibly have unspecified other impact via a crafted USB device (bnc#1066629). - CVE-2017-16536: The cx231xx_usb_probe function in drivers/media/usb/cx231xx/cx231xx-cards.c in the Linux kernel allowed local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a crafted USB device (bnc#1066606). - CVE-2017-16537: The imon_probe function in drivers/media/rc/imon.c in the Linux kernel allowed local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a crafted USB device (bnc#1066573). - CVE-2017-16645: The ims_pcu_get_cdc_union_desc function in drivers/input/misc/ims-pcu.c in the Linux kernel allowed local users to cause a denial of service (ims_pcu_parse_cdc_data out-of-bounds read and system crash) or possibly have unspecified other impact via a crafted USB device (bnc#1067132). - CVE-2017-16646: drivers/media/usb/dvb-usb/dib0700_devices.c in the Linux kernel allowed local users to cause a denial of service (BUG and system crash) or possibly have unspecified other impact via a crafted USB device (bnc#1067105). - CVE-2017-16939: The XFRM dump policy implementation in net/xfrm/xfrm_user.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (use-after-free) via a crafted SO_RCVBUF setsockopt system call in conjunction with XFRM_MSG_GETPOLICY Netlink messages (bnc#1069702). - CVE-2017-16994: The walk_hugetlb_range function in mm/pagewalk.c in the Linux kernel mishandled holes in hugetlb ranges, which allowed local users to obtain sensitive information from uninitialized kernel memory via crafted use of the mincore() system call (bnc#1069996). - CVE-2017-17448: net/netfilter/nfnetlink_cthelper.c in the Linux kernel did not require the CAP_NET_ADMIN capability for new, get, and del operations, which allowed local users to bypass intended access restrictions because the nfnl_cthelper_list data structure is shared across all net namespaces (bnc#1071693). - CVE-2017-17449: The __netlink_deliver_tap_skb function in net/netlink/af_netlink.c in the Linux kernel did not restrict observations of Netlink messages to a single net namespace, which allowed local users to obtain sensitive information by leveraging the CAP_NET_ADMIN capability to sniff an nlmon interface for all Netlink activity on the system (bnc#1071694). - CVE-2017-17450: net/netfilter/xt_osf.c in the Linux kernel did not require the CAP_NET_ADMIN capability for add_callback and remove_callback operations, which allowed local users to bypass intended access restrictions because the xt_osf_fingers data structure is shared across all net namespaces (bnc#1071695). - CVE-2017-7482: Fixed an overflow when decoding a krb5 principal. (bnc#1046107). - CVE-2017-8824: The dccp_disconnect function in net/dccp/proto.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (use-after-free) via an AF_UNSPEC connect system call during the DCCP_LISTEN state (bnc#1070771). The following non-security bugs were fixed : - adm80211: return an error if adm8211_alloc_rings() fails (bsc#1031717). - adv7604: Initialize drive strength to default when using DT (bnc#1012382). - af_netlink: ensure that NLMSG_DONE never fails in dumps (bnc#1012382). - alsa: caiaq: Fix stray URB at probe error path (bnc#1012382). - alsa: hda: Add Raven PCI ID (bnc#1012382). - alsa: hda - Apply ALC269_FIXUP_NO_SHUTUP on HDA_FIXUP_ACT_PROBE (bnc#1012382). - alsa: hda/ca0132 - Fix memory leak at error path (bsc#1031717). - alsa: hda - fix headset mic problem for Dell machines with alc236 (bnc#1012382). - alsa: hda - No loopback on ALC299 codec (git-fixes). - alsa: hda/realtek: Add headset mic support for Intel NUC Skull Canyon (bsc#1031717). - alsa: hda/realtek - Add new codec ID ALC299 (bnc#1012382). - alsa: hda/realtek - Add support for ALC236/ALC3204 (bnc#1012382). - alsa: hda/realtek - Fix ALC700 family no sound issue (bsc#1031717). - alsa: hda: Remove superfluous

  - ceph: unlock dangling spinlock in try_flush_caps()
    (bsc#1065639).

  - cgroup, net_cls: iterate the fds of only the tasks which
    are being migrated (bnc#1064926).

  - cifs: add build_path_from_dentry_optional_prefix()
    (fate#323482)

  - cifs: Add capability to decrypt big read responses
    (FATE#324404). Allow to decrypt transformed packets that
    are bigger than the big buffer size. In particular it is
    used for read responses that can only exceed the big
    buffer size.

  - cifs: Add capability to transform requests before
    sending (FATE#324404). This will allow us to do protocol
    specific tranformations of packets before sending to the
    server. For SMB3 it can be used to support encryption.

  - cifs: Add copy into pages callback for a read operation
    (FATE#324404). Since we have two different types of
    reads (pagecache and direct) we need to process such
    responses differently after decryption of a packet. The
    change allows to specify a callback that copies a read
    payload data into preallocated pages.

  - cifs: Add mid handle callback (FATE#324404). We need to
    process read responses differently because the data
    should go directly into preallocated pages. This can be
    done by specifying a mid handle callback.

  - cifs: Add soft dependencies (FATE#324404). List soft
    dependencies of cifs so that mkinitrd and dracut can
    include the required helper modules.

  - cifs: Add transform header handling callbacks
    (FATE#324404). We need to recognize and parse
    transformed packets in demultiplex thread to find a
    corresponsing mid and process it further.

  - cifs: add use_ipc flag to SMB2_ioctl() (fate#323482)

  - cifs: Allow to switch on encryption with seal mount
    option (FATE#324404). This allows users to inforce
    encryption for SMB3 shares if a server supports it.

  - cifs: check MaxPathNameComponentLength != 0 before using
    it (bnc#1012382).

  - cifs: Decrypt and process small encrypted packets
    (FATE#324404). Allow to decrypt transformed packets,
    find a corresponding mid and process as usual further.

  - cifs: do not bother with kmap on read_pages side
    (FATE#324404). just do ITER_BVEC recvmsg

  - cifs: Enable encryption during session setup phase
    (FATE#324404). In order to allow encryption on SMB
    connection we need to exchange a session key and
    generate encryption and decryption keys.

  - cifs: Encrypt SMB3 requests before sending
    (FATE#324404). This change allows to encrypt packets if
    it is required by a server for SMB sessions or tree
    connections.

  - cifs: fix circular locking dependency (bsc#1064701).

  - cifs: Fix some return values in case of error in
    'crypt_message' (fate#324404).

  - cifs: Fix sparse warnings (fate#323482)

  - cifs: implement get_dfs_refer for SMB2+ (fate#323482)

  - cifs: let ses->ipc_tid hold smb2 TreeIds (fate#323482)

  - cifs: Make send_cancel take rqst as argument
    (FATE#324404).

  - cifs: Make SendReceive2() takes resp iov (FATE#324404).
    Now SendReceive2 frees the first iov and returns a
    response buffer in it that increases a code complexity.
    Simplify this by making a caller responsible for freeing
    request buffer itself and returning a response buffer in
    a separate iov.

  - cifs: move DFS response parsing out of SMB1 code
    (fate#323482)

  - cifs: no need to wank with copying and advancing iovec
    on recvmsg side either (FATE#324404).

  - cifs: Only select the required crypto modules
    (FATE#324404). The sha256 and cmac crypto modules are
    only needed for SMB2+, so move the select statements to
    config CIFS_SMB2. Also select CRYPTO_AES there as SMB2+
    needs it.

  - cifs: Prepare for encryption support (first part). Add
    decryption and encryption key generation. (FATE#324404).

  - cifs_readv_receive: use cifs_read_from_socket()
    (FATE#324404).

  - cifs: Reconnect expired SMB sessions (bnc#1012382).

  - cifs: remove any preceding delimiter from prefix_path
    (fate#323482)

  - cifs: Send RFC1001 length in a separate iov
    (FATE#324404). In order to simplify further encryption
    support we need to separate RFC1001 length and SMB2
    header when sending a request. Put the length field in
    iov[0] and the rest of the packet into following iovs.

  - cifs: Separate RFC1001 length processing for SMB2 read
    (FATE#324404). Allocate and initialize SMB2 read request
    without RFC1001 length field to directly call
    cifs_send_recv() rather than SendReceive2() in a read
    codepath.

  - cifs: Separate SMB2 header structure (FATE#324404). In
    order to support compounding and encryption we need to
    separate RFC1001 length field and SMB2 header structure
    because the protocol treats them differently. This
    change will allow to simplify parsing of such complex
    SMB2 packets further.

  - cifs: Separate SMB2 sync header processing
    (FATE#324404). Do not process RFC1001 length in
    smb2_hdr_assemble() because it is not a part of SMB2
    header. This allows to cleanup the code and adds a
    possibility combine several SMB2 packets into one for
    compounding.

  - cifs: set signing flag in SMB2+ TreeConnect if needed
    (fate#323482)

  - cifs: Simplify SMB2 and SMB311 dependencies
    (FATE#324404). * CIFS_SMB2 depends on CIFS, which
    depends on INET and selects NLS. So these dependencies
    do not need to be repeated for CIFS_SMB2. * CIFS_SMB311
    depends on CIFS_SMB2, which depends on INET. So this
    dependency does not need to be repeated for CIFS_SMB311.

    (fate#323482)

    descriptionAccording to the versions of the kernel packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities : - The kernel package contains the Linux kernel (vmlinuz), the core of any Linux operating system. The kernel handles the basic functions of the operating system: memory allocation, process allocation, device input and output, etc.Security Fix(es):A flaw named FragmentSmack was found in the way the Linux kernel handled reassembly of fragmented IPv4 and IPv6 packets. A remote attacker could use this flaw to trigger time and calculation expensive fragment reassembly algorithm by sending specially crafted packets which could lead to a CPU saturation and hence a denial of service on the system.(CVE-2018-5391)Multiple out-of-bounds write flaws were found in the way the Cherry Cymotion keyboard driver, KYE/Genius device drivers, Logitech device drivers, Monterey Genius KB29E keyboard driver, Petalynx Maxter remote control driver, and Sunplus wireless desktop driver handled HID reports with an invalid report descriptor size. An attacker with physical access to the system could use either of these flaws to write data past an allocated memory buffer.(CVE-2014-3184)The __get_data_block function in fs/f2fs/data.c in the Linux kernel before 4.11 allows local users to cause a denial of service (integer overflow and loop) via crafted use of the open and fallocate system calls with an FS_IOC_FIEMAP ioctl.(CVE-2017-18257)netetfilter/xt_osf.c in the Linux kernel through 4.14.4 does not require the CAP_NET_ADMIN capability for add_callback and remove_callback operations. This allows local users to bypass intended access restrictions because the xt_osf_fingers data structure is shared across all network namespaces.(CVE-2017-17450)A denial of service flaw was discovered in the Linux kernel, where a race condition caused a NULL pointer dereference in the RDS socket-creation code. A local attacker could use this flaw to create a situation in which a NULL pointer crashed the kernel.(CVE-2015-7990)An issue was discovered in the Linux kernel before 4.19.9. The USB subsystem mishandles size checks during the reading of an extra descriptor, related to __usb_get_extra_descriptor in drivers/usb/core/usb.c.(CVE-2018-20169)mm/memory.c in the Linux kernel before 4.1.4 mishandles anonymous pages, which allows local users to gain privileges or cause a denial of service (page tainting) via a crafted application that triggers writing to page zero.(CVE-2015-3288)The ovl_setattr function in fs/overlayfs/inode.c in the Linux kernel through 4.3.3 attempts to merge distinct setattr operations, which allows local users to bypass intended access restrictions and modify the attributes of arbitrary overlay files via a crafted application.(CVE-2015-8660)A flaw was found in the Linux kernel where a local user with a shell account can abuse the userfaultfd syscall when using hugetlbfs. A missing size check in hugetlb_mcopy_atomic_pte could create an invalid inode variable, leading to a kernel panic.(CVE-2017-15128)An integer overflow flaw was found in the way the lzo1x_decompress_safe() function of the Linux kernel

    device drivers, Monterey Genius KB29E keyboard driver,
    Petalynx Maxter remote control driver, and Sunplus
    wireless desktop driver handled HID reports with an
    invalid report descriptor size. An attacker with
    physical access to the system could use either of these
    flaws to write data past an allocated memory
    buffer.(CVE-2014-3184)The __get_data_block function in
    fs/f2fs/data.c in the Linux kernel before 4.11 allows
    local users to cause a denial of service (integer
    overflow and loop) via crafted use of the open and
    fallocate system calls with an FS_IOC_FIEMAP
    ioctl.(CVE-2017-18257)netetfilter/xt_osf.c in the Linux
    kernel through 4.14.4 does not require the
    CAP_NET_ADMIN capability for add_callback and
    remove_callback operations. This allows local users to
    bypass intended access restrictions because the
    xt_osf_fingers data structure is shared across all
    network namespaces.(CVE-2017-17450)A denial of service
    flaw was discovered in the Linux kernel, where a race
    condition caused a NULL pointer dereference in the RDS
    socket-creation code. A local attacker could use this
    flaw to create a situation in which a NULL pointer
    crashed the kernel.(CVE-2015-7990)An issue was
    discovered in the Linux kernel before 4.19.9. The USB
    subsystem mishandles size checks during the reading of
    an extra descriptor, related to
    __usb_get_extra_descriptor in
    drivers/usb/core/usb.c.(CVE-2018-20169)mm/memory.c in
    the Linux kernel before 4.1.4 mishandles anonymous
    pages, which allows local users to gain privileges or
    cause a denial of service (page tainting) via a crafted
    application that triggers writing to page
    zero.(CVE-2015-3288)The ovl_setattr function in
    fs/overlayfs/inode.c in the Linux kernel through 4.3.3
    attempts to merge distinct setattr operations, which
    allows local users to bypass intended access
    restrictions and modify the attributes of arbitrary
    overlay files via a crafted
    application.(CVE-2015-8660)A flaw was found in the
    Linux kernel where a local user with a shell account
    can abuse the userfaultfd syscall when using hugetlbfs.
    A missing size check in hugetlb_mcopy_atomic_pte could
    create an invalid inode variable, leading to a kernel
    panic.(CVE-2017-15128)An integer overflow flaw was
    found in the way the lzo1x_decompress_safe() function
    of the Linux kernel's LZO implementation processed
    Literal Runs. A local attacker could, in extremely rare
    cases, use this flaw to crash the system or,
    potentially, escalate their privileges on the
    system.(CVE-2014-4608)It was found that Linux kernel's
    ptrace subsystem did not properly sanitize the
    address-space-control bits when the program-status word
    (PSW) was being set. On IBM S/390 systems, a local,
    unprivileged user could use this flaw to set
    address-space-control bits to the kernel space, and
    thus gain read and write access to kernel
    memory.(CVE-2014-3534)A use-after-free flaw was found
    in the Linux kernel's file system encryption
    implementation. A local user could revoke keyring keys
    being used for ext4, f2fs, or ubifs encryption, causing
    a denial of service on the system.(CVE-2017-7374)The
    usbip_recv_xbuff function in
    drivers/usb/usbip/usbip_common.c in the Linux kernel
    before 4.5.3 allows remote attackers to cause a denial
    of service (out-of-bounds write) or possibly have
    unspecified other impact via a crafted length value in
    a USB/IP packet.(CVE-2016-3955)A flaw was found in the
    patches used to fix the 'dirtycow' vulnerability
    (CVE-2016-5195). An attacker, able to run local code,
    can exploit a race condition in transparent huge pages
    to modify usually read-only huge
    pages.(CVE-2017-1000405)The aio_mount function in
    fs/aio.c in the Linux kernel does not properly restrict
    execute access, which makes it easier for local users
    to bypass intended SELinux W^X policy
    restrictions.(CVE-2016-10044)The Serial Attached SCSI
    (SAS) implementation in the Linux kernel mishandles a
    mutex within libsas. This allows local users to cause a
    denial of service (deadlock) by triggering certain
    error-handling code.(CVE-2017-18232)A use-after-free
    vulnerability was found in tcp_xmit_retransmit_queue
    and other tcp_* functions. This condition could allow
    an attacker to send an incorrect selective
    acknowledgment to existing connections, possibly
    resetting a connection.(CVE-2016-6828)The instruction
    decoder in arch/x86/kvm/emulate.c in the KVM subsystem
    in the Linux kernel before 3.18-rc2 does not properly
    handle invalid instructions, which allows guest OS
    users to cause a denial of service (NULL pointer
    dereference and host OS crash) via a crafted
    application that triggers (1) an improperly fetched
    instruction or (2) an instruction that occupies too
    many bytes. NOTE: this vulnerability exists because of
    an incomplete fix for CVE-2014-8480.(CVE-2014-8481)The
    snd_compress_check_input function in
    sound/core/compress_offload.c in the ALSA subsystem in
    the Linux kernel before 3.17 does not properly check
    for an integer overflow, which allows local users to
    cause a denial of service (insufficient memory
    allocation) or possibly have unspecified other impact
    via a crafted SNDRV_COMPRESS_SET_PARAMS ioctl
    call.(CVE-2014-9904)The resv_map_release function in
    mm/hugetlb.c in the Linux kernel, through 4.15.7,
    allows local users to cause a denial of service (BUG)
    via a crafted application that makes mmap system calls
    and has a large pgoff argument to the remap_file_pages
    system call.(CVE-2018-7740)

    descriptionSeveral vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks. - CVE-2017-8824 Mohamed Ghannam discovered that the DCCP implementation did not correctly manage resources when a socket is disconnected and reconnected, potentially leading to a use-after-free. A local user could use this for denial of service (crash or data corruption) or possibly for privilege escalation. On systems that do not already have the dccp module loaded, this can be mitigated by disabling it:echo >> /etc/modprobe.d/disable-dccp.conf install dccp false - CVE-2017-16538 Andrey Konovalov reported that the dvb-usb-lmedm04 media driver did not correctly handle some error conditions during initialisation. A physically present user with a specially designed USB device can use this to cause a denial of service (crash). - CVE-2017-16644 Andrey Konovalov reported that the hdpvr media driver did not correctly handle some error conditions during initialisation. A physically present user with a specially designed USB device can use this to cause a denial of service (crash). - CVE-2017-16995 Jann Horn discovered that the Extended BPF verifier did not correctly model the behaviour of 32-bit load instructions. A local user can use this for privilege escalation. - CVE-2017-17448 Kevin Cernekee discovered that the netfilter subsystem allowed users with the CAP_NET_ADMIN capability in any user namespace, not just the root namespace, to enable and disable connection tracking helpers. This could lead to denial of service, violation of network security policy, or have other impact. - CVE-2017-17449 Kevin Cernekee discovered that the netlink subsystem allowed users with the CAP_NET_ADMIN capability in any user namespace to monitor netlink traffic in all net namespaces, not just those owned by that user namespace. This could lead to exposure of sensitive information. - CVE-2017-17450 Kevin Cernekee discovered that the xt_osf module allowed users with the CAP_NET_ADMIN capability in any user namespace to modify the global OS fingerprint list. - CVE-2017-17558 Andrey Konovalov reported that that USB core did not correctly handle some error conditions during initialisation. A physically present user with a specially designed USB device can use this to cause a denial of service (crash or memory corruption), or possibly for privilege escalation. - CVE-2017-17712 Mohamed Ghannam discovered a race condition in the IPv4 raw socket implementation. A local user could use this to obtain sensitive information from the kernel. - CVE-2017-17741 Dmitry Vyukov reported that the KVM implementation for x86 would over-read data from memory when emulating an MMIO write if the kvm_mmio tracepoint was enabled. A guest virtual machine might be able to use this to cause a denial of service (crash). - CVE-2017-17805 It was discovered that some implementations of the Salsa20 block cipher did not correctly handle zero-length input. A local user could use this to cause a denial of service (crash) or possibly have other security impact. - CVE-2017-17806 It was discovered that the HMAC implementation could be used with an underlying hash algorithm that requires a key, which was not intended. A local user could use this to cause a denial of service (crash or memory corruption), or possibly for privilege escalation. - CVE-2017-17807 Eric Biggers discovered that the KEYS subsystem lacked a check for write permission when adding keys to a process

"Several vulnerabilities have been discovered in the Linux kernel that
may lead to a privilege escalation, denial of service or information
leaks.

  - CVE-2017-8824
    Mohamed Ghannam discovered that the DCCP implementation
    did not correctly manage resources when a socket is
    disconnected and reconnected, potentially leading to a
    use-after-free. A local user could use this for denial
    of service (crash or data corruption) or possibly for
    privilege escalation. On systems that do not already
    have the dccp module loaded, this can be mitigated by
    disabling it:echo >> /etc/modprobe.d/disable-dccp.conf
    install dccp false

  - CVE-2017-16538
    Andrey Konovalov reported that the dvb-usb-lmedm04 media
    driver did not correctly handle some error conditions
    during initialisation. A physically present user with a
    specially designed USB device can use this to cause a
    denial of service (crash).

  - CVE-2017-16644
    Andrey Konovalov reported that the hdpvr media driver
    did not correctly handle some error conditions during
    initialisation. A physically present user with a
    specially designed USB device can use this to cause a
    denial of service (crash).

  - CVE-2017-16995
    Jann Horn discovered that the Extended BPF verifier did
    not correctly model the behaviour of 32-bit load
    instructions. A local user can use this for privilege
    escalation.

  - CVE-2017-17448
    Kevin Cernekee discovered that the netfilter subsystem
    allowed users with the CAP_NET_ADMIN capability in any
    user namespace, not just the root namespace, to enable
    and disable connection tracking helpers. This could lead
    to denial of service, violation of network security
    policy, or have other impact.

  - CVE-2017-17449
    Kevin Cernekee discovered that the netlink subsystem
    allowed users with the CAP_NET_ADMIN capability in any
    user namespace to monitor netlink traffic in all net
    namespaces, not just those owned by that user namespace.
    This could lead to exposure of sensitive information.

  - CVE-2017-17450
    Kevin Cernekee discovered that the xt_osf module allowed
    users with the CAP_NET_ADMIN capability in any user
    namespace to modify the global OS fingerprint list.

  - CVE-2017-17558
    Andrey Konovalov reported that that USB core did not
    correctly handle some error conditions during
    initialisation. A physically present user with a
    specially designed USB device can use this to cause a
    denial of service (crash or memory corruption), or
    possibly for privilege escalation.

  - CVE-2017-17712
    Mohamed Ghannam discovered a race condition in the IPv4
    raw socket implementation. A local user could use this
    to obtain sensitive information from the kernel.

  - CVE-2017-17741
    Dmitry Vyukov reported that the KVM implementation for
    x86 would over-read data from memory when emulating an
    MMIO write if the kvm_mmio tracepoint was enabled. A
    guest virtual machine might be able to use this to cause
    a denial of service (crash).

  - CVE-2017-17805
    It was discovered that some implementations of the
    Salsa20 block cipher did not correctly handle
    zero-length input. A local user could use this to cause
    a denial of service (crash) or possibly have other
    security impact.

  - CVE-2017-17806
    It was discovered that the HMAC implementation could be
    used with an underlying hash algorithm that requires a
    key, which was not intended. A local user could use this
    to cause a denial of service (crash or memory
    corruption), or possibly for privilege escalation.

  - CVE-2017-17807
    Eric Biggers discovered that the KEYS subsystem lacked a
    check for write permission when adding keys to a
    process's default keyring. A local user could use this
    to cause a denial of service or to obtain sensitive
    information.

  - CVE-2017-17862
    Alexei Starovoitov discovered that the Extended BPF
    verifier ignored unreachable code, even though it would
    still be processed by JIT compilers. This could possibly
    be used by local users for denial of service. It also
    increases the severity of bugs in determining
    unreachable code.

  - CVE-2017-17863
    Jann Horn discovered that the Extended BPF verifier did
    not correctly model pointer arithmetic on the stack
    frame pointer. A local user can use this for privilege
    escalation.

  - CVE-2017-17864
    Jann Horn discovered that the Extended BPF verifier
    could fail to detect pointer leaks from conditional
    code. A local user could use this to obtain sensitive
    information in order to exploit other vulnerabilities.

  - CVE-2017-1000407
    Andrew Honig reported that the KVM implementation for
    Intel processors allowed direct access to host I/O port
    0x80, which is not generally safe. On some systems this
    allows a guest VM to cause a denial of service (crash)
    of the host.

  - CVE-2017-1000410
    Ben Seri reported that the Bluetooth subsystem did not
    correctly handle short EFS information elements in L2CAP
    messages. An attacker able to communicate over Bluetooth
    could use this to obtain sensitive information from the
    kernel.

The various problems in the Extended BPF verifier can be mitigated by
disabling use of Extended BPF by unprivileged users:sysctl
kernel.unprivileged_bpf_disabled=1

Debian disables unprivileged user namespaces by default, but if they
are enabled (via the kernel.unprivileged_userns_clone sysctl) then
CVE-2017-17448 can be exploited by any local user."

    NASL idOPENSUSE-2017-1391.NASL
    descriptionThe openSUSE Leap 42.3 kernel was updated to 4.4.103 to receive various security and bugfixes. The following security bugs were fixed : - CVE-2017-1000405: A bug in the THP CoW support could be used by local attackers to corrupt memory of other processes and cause them to crash (bnc#1069496). - CVE-2017-1000410: The Linux kernel was affected by a vulnerability lies in the processing of incoming L2CAP commands - ConfigRequest, and ConfigResponse messages. This info leak is a result of uninitialized stack variables that may be returned to an attacker in their uninitialized state. (bnc#1070535). - CVE-2017-11600: net/xfrm/xfrm_policy.c in the Linux kernel did not ensure that the dir value of xfrm_userpolicy_id is XFRM_POLICY_MAX or less, which allowed local users to cause a denial of service (out-of-bounds access) or possibly have unspecified other impact via an XFRM_MSG_MIGRATE xfrm Netlink message (bnc#1050231). - CVE-2017-12193: The assoc_array_insert_into_terminal_node function in lib/assoc_array.c in the Linux kernel mishandled node splitting, which allowed local users to cause a denial of service (NULL pointer dereference and panic) via a crafted application, as demonstrated by the keyring key type, and key addition and link creation operations (bnc#1066192). - CVE-2017-15115: The sctp_do_peeloff function in net/sctp/socket.c in the Linux kernel did not check whether the intended netns is used in a peel-off action, which allowed local users to cause a denial of service (use-after-free and system crash) or possibly have unspecified other impact via crafted system calls (bnc#1068671). - CVE-2017-16528: sound/core/seq_device.c in the Linux kernel allowed local users to cause a denial of service (snd_rawmidi_dev_seq_free use-after-free and system crash) or possibly have unspecified other impact via a crafted USB device (bnc#1066629). - CVE-2017-16536: The cx231xx_usb_probe function in drivers/media/usb/cx231xx/cx231xx-cards.c in the Linux kernel allowed local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a crafted USB device (bnc#1066606). - CVE-2017-16537: The imon_probe function in drivers/media/rc/imon.c in the Linux kernel allowed local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a crafted USB device (bnc#1066573). - CVE-2017-16645: The ims_pcu_get_cdc_union_desc function in drivers/input/misc/ims-pcu.c in the Linux kernel allowed local users to cause a denial of service (ims_pcu_parse_cdc_data out-of-bounds read and system crash) or possibly have unspecified other impact via a crafted USB device (bnc#1067132). - CVE-2017-16646: drivers/media/usb/dvb-usb/dib0700_devices.c in the Linux kernel allowed local users to cause a denial of service (BUG and system crash) or possibly have unspecified other impact via a crafted USB device (bnc#1067105). - CVE-2017-16939: The XFRM dump policy implementation in net/xfrm/xfrm_user.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (use-after-free) via a crafted SO_RCVBUF setsockopt system call in conjunction with XFRM_MSG_GETPOLICY Netlink messages (bnc#1069702). - CVE-2017-16994: The walk_hugetlb_range function in mm/pagewalk.c in the Linux kernel mishandled holes in hugetlb ranges, which allowed local users to obtain sensitive information from uninitialized kernel memory via crafted use of the mincore() system call (bnc#1069996). - CVE-2017-17448: net/netfilter/nfnetlink_cthelper.c in the Linux kernel did not require the CAP_NET_ADMIN capability for new, get, and del operations, which allowed local users to bypass intended access restrictions because the nfnl_cthelper_list data structure is shared across all net namespaces (bnc#1071693). - CVE-2017-17449: The __netlink_deliver_tap_skb function in net/netlink/af_netlink.c in the Linux kernel did not restrict observations of Netlink messages to a single net namespace, which allowed local users to obtain sensitive information by leveraging the CAP_NET_ADMIN capability to sniff an nlmon interface for all Netlink activity on the system (bnc#1071694). - CVE-2017-17450: net/netfilter/xt_osf.c in the Linux kernel did not require the CAP_NET_ADMIN capability for add_callback and remove_callback operations, which allowed local users to bypass intended access restrictions because the xt_osf_fingers data structure is shared across all net namespaces (bnc#1071695). - CVE-2017-7482: Fixed an overflow when decoding a krb5 principal. (bnc#1046107). - CVE-2017-8824: The dccp_disconnect function in net/dccp/proto.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (use-after-free) via an AF_UNSPEC connect system call during the DCCP_LISTEN state (bnc#1070771).

    descriptionAccording to the versions of the parallels-server-bm-release / vzkernel / etc packages installed, the Virtuozzo installation on the remote host is affected by the following vulnerabilities : - An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimization). There are three primary variants of the issue which differ in the way the speculative execution can be exploited. Variant CVE-2017-5754 relies on the fact that, on impacted microprocessors, during speculative execution of instruction permission faults, exception generation triggered by a faulting access is suppressed until the retirement of the whole instruction block. In a combination with the fact that memory accesses may populate the cache even when the block is being dropped and never committed (executed), an unprivileged local attacker could use this flaw to read privileged (kernel space) memory by conducting targeted cache side-channel attacks. NOTE: This update fixes the 32-bit compatibility layer on x86-64 processors, i.e. when 32-bit containers are executed on 64-bit processors. - A bug in the 32-bit compatibility layer of the ioctl handling code of the v4l2 video driver in the Linux kernel has been found. A memory protection mechanism ensuring that user-provided buffers always point to a userspace memory were disabled, allowing destination address to be in a kernel space. This flaw could be exploited by an attacker to overwrite a kernel memory from an unprivileged userspace process, leading to privilege escalation. - The KEYS subsystem in the Linux kernel omitted an access-control check when writing a key to the current task

    descriptionSeveral vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks. - CVE-2017-5754 Multiple researchers have discovered a vulnerability in Intel processors, enabling an attacker controlling an unprivileged process to read memory from arbitrary addresses, including from the kernel and all other processes running on the system. This specific attack has been named Meltdown and is addressed in the Linux kernel for the Intel x86-64 architecture by a patch set named Kernel Page Table Isolation, enforcing a near complete separation of the kernel and userspace address maps and preventing the attack. This solution might have a performance impact, and can be disabled at boot time by passing pti=off to the kernel command line. - CVE-2017-8824 Mohamed Ghannam discovered that the DCCP implementation did not correctly manage resources when a socket is disconnected and reconnected, potentially leading to a use-after-free. A local user could use this for denial of service (crash or data corruption) or possibly for privilege escalation. On systems that do not already have the dccp module loaded, this can be mitigated by disabling it:echo >> /etc/modprobe.d/disable-dccp.conf install dccp false - CVE-2017-15868 Al Viro found that the Bluebooth Network Encapsulation Protocol (BNEP) implementation did not validate the type of the second socket passed to the BNEPCONNADD ioctl(), which could lead to memory corruption. A local user with the CAP_NET_ADMIN capability can use this for denial of service (crash or data corruption) or possibly for privilege escalation. - CVE-2017-16538 Andrey Konovalov reported that the dvb-usb-lmedm04 media driver did not correctly handle some error conditions during initialisation. A physically present user with a specially designed USB device can use this to cause a denial of service (crash). - CVE-2017-16939 Mohamed Ghannam reported (through Beyond Security

A local attacker could use this to expose sensitive information (kernel memory). (CVE-2017-14156) ChunYu Wang discovered that the iSCSI transport implementation in the Linux kernel did not properly validate data structures. A local attacker could use this to cause a denial of service (system crash). (CVE-2017-14489) James Patrick-Evans discovered a race condition in the LEGO USB Infrared Tower driver in the Linux kernel. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-15102) ChunYu Wang discovered that a use-after-free vulnerability existed in the SCTP protocol implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code, (CVE-2017-15115) It was discovered that the key management subsystem in the Linux kernel did not properly handle NULL payloads with non-zero length values. A local attacker could use this to cause a denial of service (system crash). (CVE-2017-15274) It was discovered that the Bluebooth Network Encapsulation Protocol (BNEP) implementation in the Linux kernel did not validate the type of socket passed in the BNEPCONNADD ioctl(). A local attacker with the CAP_NET_ADMIN privilege could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-15868) Andrey Konovalov discovered a use-after-free vulnerability in the USB serial console driver in the Linux kernel. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-16525) It was discovered that the netfilter passive OS fingerprinting (xt_osf) module did not properly perform access control checks. A local attacker could improperly modify the systemwide OS fingerprint list. (CVE-2017-17450) It was discovered that the HMAC implementation did not validate the state of the underlying cryptographic hash algorithm. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-17806) Denys Fedoryshchenko discovered a use-after-free vulnerability in the netfilter xt_TCPMSS filter of the Linux kernel. A remote attacker could use this to cause a denial of service (system crash). (CVE-2017-18017) Gareth Evans discovered that the shm IPC subsystem in the Linux kernel did not properly restrict mapping page zero. A local privileged attacker could use this to execute arbitrary code. (CVE-2017-5669) It was discovered that an integer overflow vulnerability existing in the IPv6 implementation in the Linux kernel. A local attacker could use this to cause a denial of service (infinite loop). (CVE-2017-7542) Tommi Rantala and Brad Spengler discovered that the memory manager in the Linux kernel did not properly enforce the CONFIG_STRICT_DEVMEM protection mechanism. A local attacker with access to /dev/mem could use this to expose sensitive information or possibly execute arbitrary code. (CVE-2017-7889) Mohamed Ghannam discovered a use-after-free vulnerability in the DCCP protocol implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-8824) Mohamed Ghannam discovered a NULL pointer dereference in the RDS (Reliable Datagram Sockets) protocol implementation of the Linux kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2018-5333) Fan Long Fei discovered that a race condition existed in loop block device implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-5344) USN-3524-1 mitigated CVE-2017-5754 (Meltdown) for the amd64 architecture in Ubuntu 14.04 LTS. This update provides the corresponding mitigations for the ppc64el architecture. Original advisory details : Jann Horn discovered that microprocessors utilizing speculative execution and indirect branch prediction may allow unauthorized memory reads via sidechannel attacks. This flaw is known as Meltdown. A local attacker could use this to expose sensitive information, including kernel memory. (CVE-2017-5754). Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
