    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 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 remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has kernel packages installed that are affected by multiple vulnerabilities: - Integer overflow in the aio_setup_single_vector function in fs/aio.c in the Linux kernel 4.0 allows local users to cause a denial of service or possibly have unspecified other impact via a large AIO iovec. NOTE: this vulnerability exists because of a CVE-2012-6701 regression. (CVE-2015-8830) - A weakness was found in the Linux ASLR implementation. Any user able to running 32-bit applications in a x86 machine can disable ASLR by setting the RLIMIT_STACK resource to unlimited. (CVE-2016-3672) - The xc2028_set_config function in drivers/media/tuners/tuner-xc2028.c in the Linux kernel before 4.6 allows local users to gain privileges or cause a denial of service (use-after-free) via vectors involving omission of the firmware name from a certain data structure. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely. (CVE-2016-7913) - Use-after-free vulnerability in the snd_pcm_info() function in the ALSA subsystem in the Linux kernel allows attackers to induce a kernel memory corruption and possibly crash or lock up a system. Due to the nature of the flaw, a privilege escalation cannot be fully ruled out, although we believe it is unlikely. (CVE-2017-0861) - A reachable assertion failure flaw was found in the Linux kernel built with KVM virtualisation(CONFIG_KVM) support with Virtual Function I/O feature (CONFIG_VFIO) enabled. This failure could occur if a malicious guest device sent a virtual interrupt (guest IRQ) with a larger (>1024) index value. (CVE-2017-1000252) - Linux kernel Virtualization Module (CONFIG_KVM) for the Intel processor family (CONFIG_KVM_INTEL) is vulnerable to a DoS issue. It could occur if a guest was to flood the I/O port 0x80 with write requests. A guest user could use this flaw to crash the host kernel resulting in DoS. (CVE-2017-1000407) - A flaw was found in the processing of incoming L2CAP bluetooth commands. Uninitialized stack variables can be sent to an attacker leaking data in kernel address space. (CVE-2017-1000410) - A race condition was found in the Linux kernel before version 4.11-rc1 in

"The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has kernel packages installed that are affected by
multiple vulnerabilities:

  - Integer overflow in the aio_setup_single_vector function
    in fs/aio.c in the Linux kernel 4.0 allows local users
    to cause a denial of service or possibly have
    unspecified other impact via a large AIO iovec. NOTE:
    this vulnerability exists because of a CVE-2012-6701
    regression. (CVE-2015-8830)

  - A weakness was found in the Linux ASLR implementation.
    Any user able to running 32-bit applications in a x86
    machine can disable ASLR by setting the RLIMIT_STACK
    resource to unlimited. (CVE-2016-3672)

  - The xc2028_set_config function in
    drivers/media/tuners/tuner-xc2028.c in the Linux kernel
    before 4.6 allows local users to gain privileges or
    cause a denial of service (use-after-free) via vectors
    involving omission of the firmware name from a certain
    data structure. Due to the nature of the flaw, privilege
    escalation cannot be fully ruled out, although we
    believe it is unlikely. (CVE-2016-7913)

  - Use-after-free vulnerability in the snd_pcm_info()
    function in the ALSA subsystem in the Linux kernel
    allows attackers to induce a kernel memory corruption
    and possibly crash or lock up a system. Due to the
    nature of the flaw, a privilege escalation cannot be
    fully ruled out, although we believe it is unlikely.
    (CVE-2017-0861)

  - A reachable assertion failure flaw was found in the
    Linux kernel built with KVM virtualisation(CONFIG_KVM)
    support with Virtual Function I/O feature (CONFIG_VFIO)
    enabled. This failure could occur if a malicious guest
    device sent a virtual interrupt (guest IRQ) with a
    larger (>1024) index value. (CVE-2017-1000252)

  - Linux kernel Virtualization Module (CONFIG_KVM) for the
    Intel processor family (CONFIG_KVM_INTEL) is vulnerable
    to a DoS issue. It could occur if a guest was to flood
    the I/O port 0x80 with write requests. A guest user
    could use this flaw to crash the host kernel resulting
    in DoS. (CVE-2017-1000407)

  - A flaw was found in the processing of incoming L2CAP
    bluetooth commands. Uninitialized stack variables can be
    sent to an attacker leaking data in kernel address
    space. (CVE-2017-1000410)

  - A race condition was found in the Linux kernel before
    version 4.11-rc1 in 'fs/timerfd.c' file which allows a
    local user to cause a kernel list corruption or use-
    after-free via simultaneous operations with a file
    descriptor which leverage improper 'might_cancel'
    queuing. An unprivileged local user could use this flaw
    to cause a denial of service of the system. Due to the
    nature of the flaw, privilege escalation cannot be fully
    ruled out, although we believe it is unlikely.
    (CVE-2017-10661)

  - Linux kernel built with the KVM visualization support
    (CONFIG_KVM), with nested visualization (nVMX) feature
    enabled (nested=1), is vulnerable to a crash due to
    disabled external interrupts. As L2 guest could access
    (r/w) hardware CR8 register of the host(L0). In a nested
    visualization setup, L2 guest user could use this flaw
    to potentially crash the host(L0) resulting in DoS.
    (CVE-2017-12154)

  - It was found that in the Linux kernel through v4.14-rc5,
    bio_map_user_iov() and bio_unmap_user() in 'block/bio.c'
    do unbalanced pages refcounting if IO vector has small
    consecutive buffers belonging to the same page.
    bio_add_pc_page() merges them into one, but the page
    reference is never dropped, causing a memory leak and
    possible system lockup due to out-of-memory condition.
    (CVE-2017-12190)

  - A flaw was found in the Linux kernel's implementation of
    valid_master_desc() in which a memory buffer would be
    compared to a userspace value with an incorrect size of
    comparison. By bruteforcing the comparison, an attacker
    could determine what was in memory after the description
    and possibly obtain sensitive information from kernel
    memory. (CVE-2017-13305)

  - A use-after-free vulnerability was found in a network
    namespaces code affecting the Linux kernel since
    v4.0-rc1 through v4.15-rc5. The function
    get_net_ns_by_id() does not check for the net::count
    value after it has found a peer network in netns_ids idr
    which could lead to double free and memory corruption.
    This vulnerability could allow an unprivileged local
    user to induce kernel memory corruption on the system,
    leading to a crash. Due to the nature of the flaw,
    privilege escalation cannot be fully ruled out, although
    it is thought to be unlikely. (CVE-2017-15129)

  - A use-after-free vulnerability was found when issuing an
    ioctl to a sound device. This could allow a user to
    exploit a race condition and create memory corruption or
    possibly privilege escalation. (CVE-2017-15265)

  - A flaw was found in the implementation of associative
    arrays where the add_key systemcall and KEYCTL_UPDATE
    operations allowed for a NULL payload with a nonzero
    length. When accessing the payload within this length
    parameters value, an unprivileged user could trivially
    cause a NULL pointer dereference (kernel oops).
    (CVE-2017-15274)

  - The net/netfilter/nfnetlink_cthelper.c function in the
    Linux kernel through 4.14.4 does not require the
    CAP_NET_ADMIN capability for new, get, and del
    operations. This 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, does not restrict observations of Netlink
    messages to a single net namespace, when CONFIG_NLMON is
    enabled. This 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)

  - 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. This allows local users
    to cause a denial of service, due to out-of-bounds write
    access, or possibly have unspecified other impact via a
    crafted USB device. Due to the nature of the flaw,
    privilege escalation cannot be fully ruled out, although
    we believe it is unlikely. (CVE-2017-17558)

  - The Salsa20 encryption algorithm in the Linux kernel,
    before 4.14.8, does not correctly handle zero-length
    inputs. This allows a local attacker the ability to use
    the AF_ALG-based skcipher interface to cause a denial of
    service (uninitialized-memory free and kernel crash) or
    have an 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 are
    vulnerable. (CVE-2017-17805)

  - The tcpmss_mangle_packet function in
    net/netfilter/xt_TCPMSS.c in the Linux kernel before
    4.11, and 4.9.x before 4.9.36, allows remote attackers
    to cause a denial of service (use-after-free and memory
    corruption) or possibly have unspecified other impact by
    leveraging the presence of xt_TCPMSS in an iptables
    action. Due to the nature of the flaw, privilege
    escalation cannot be fully ruled out, although we
    believe it is unlikely. (CVE-2017-18017)

  - The Linux kernel, before version 4.14.3, is vulnerable
    to a denial of service in
    drivers/md/dm.c:dm_get_from_kobject() which can be
    caused by local users leveraging a race condition with
    __dm_destroy() during creation and removal of DM
    devices. Only privileged local users (with CAP_SYS_ADMIN
    capability) can directly perform the ioctl operations
    for dm device creation and removal and this would
    typically be outside the direct control of the
    unprivileged attacker. (CVE-2017-18203)

  - The madvise_willneed function in the Linux kernel allows
    local users to cause a denial of service (infinite loop)
    by triggering use of MADVISE_WILLNEED for a DAX mapping.
    (CVE-2017-18208)

  - A flaw was found where the kernel truncated the value
    used to indicate the size of a buffer which it would
    later become zero using an untruncated value. This can
    corrupt memory outside of the original allocation.
    (CVE-2017-9725)

  - In the Linux kernel versions 4.12, 3.10, 2.6, and
    possibly earlier, a race condition vulnerability exists
    in the sound system allowing for a potential deadlock
    and memory corruption due to use-after-free condition
    and thus denial of service. Due to the nature of the
    flaw, privilege escalation cannot be fully ruled out,
    although we believe it is unlikely. (CVE-2018-1000004)

  - Improper validation in the bnx2x network card driver of
    the Linux kernel version 4.15 can allow for denial of
    service (DoS) attacks via a packet with a gso_size
    larger than ~9700 bytes. Untrusted guest VMs can exploit
    this vulnerability in the host machine, causing a crash
    in the network card. (CVE-2018-1000026)

  - By mmap()ing a FUSE-backed file onto a process's memory
    containing command line arguments (or environment
    strings), an attacker can cause utilities from psutils
    or procps (such as ps, w) or any other program which
    makes a read() call to the /proc//cmdline (or
    /proc//environ) files to block indefinitely (denial
    of service) or for some controlled time (as a
    synchronization primitive for other attacks).
    (CVE-2018-1120)

  - A null pointer dereference in dccp_write_xmit() function
    in net/dccp/output.c in the Linux kernel allows a local
    user to cause a denial of service by a number of certain
    crafted system calls. (CVE-2018-1130)

  - An issue was discovered in the proc_pid_stack function
    in fs/proc/base.c in the Linux kernel. An attacker with
    a local account can trick the stack unwinder code to
    leak stack contents to userspace. The fix allows only
    root to inspect the kernel stack of an arbitrary task.
    (CVE-2018-17972)

  - A flaw was found in the Linux kernel with files on tmpfs
    and hugetlbfs. An attacker is able to bypass file
    permissions on filesystems mounted with tmpfs/hugetlbs
    to modify a file and possibly disrupt normal system
    behavior. At this time there is an understanding there
    is no crash or privilege escalation but the impact of
    modifications on these filesystems of files in
    production systems may have adverse affects.
    (CVE-2018-18397)

  - In the Linux kernel before 4.17, a local attacker able
    to set attributes on an xfs filesystem could make this
    filesystem non-operational until the next mount by
    triggering an unchecked error condition during an xfs
    attribute change, because xfs_attr_shortform_addname in
    fs/xfs/libxfs/xfs_attr.c mishandles ATTR_REPLACE
    operations with conversion of an attr from short to long
    form. (CVE-2018-18690)

  - Modern operating systems implement virtualization of
    physical memory to efficiently use available system
    resources and provide inter-domain protection through
    access control and isolation. The L1TF issue was found
    in the way the x86 microprocessor designs have
    implemented speculative execution of instructions (a
    commonly used performance optimization) in combination
    with handling of page-faults caused by terminated
    virtual to physical address resolving process. As a
    result, an unprivileged attacker could use this flaw to
    read privileged memory of the kernel or other processes
    and/or cross guest/host boundaries to read host memory
    by conducting targeted cache side-channel attacks.
    (CVE-2018-3646)

  - A flaw was found in the Linux kernel's handling of
    loopback devices. An attacker, who has permissions to
    setup loopback disks, may create a denial of service or
    other unspecified actions. (CVE-2018-5344)

  - The acpi_smbus_hc_add function in drivers/acpi/sbshc.c
    in the Linux kernel, through 4.14.15, allows local users
    to obtain sensitive address information by reading dmesg
    data from an SBS HC printk call. (CVE-2018-5750)

  - An error in the _sctp_make_chunk() function
    (net/sctp/sm_make_chunk.c) when handling SCTP, packet
    length can be exploited by a malicious local user to
    cause a kernel crash and a DoS. (CVE-2018-5803)

  - In the function wmi_set_ie() in the Linux kernel the
    length validation code does not handle unsigned integer
    overflow properly. As a result, a large value of the
    ie_len argument can cause a buffer overflow and thus a
    memory corruption leading to a system crash or other or
    unspecified impact. Due to the nature of the flaw,
    privilege escalation cannot be fully ruled out, although
    we believe it is unlikely. (CVE-2018-5848)

  - ALSA sequencer core initializes the event pool on demand
    by invoking snd_seq_pool_init() when the first write
    happens and the pool is empty. A user can reset the pool
    size manually via ioctl concurrently, and this may lead
    to UAF or out-of-bound access. (CVE-2018-7566)

  - A possible memory corruption due to a type confusion was
    found in the Linux kernel in the sk_clone_lock()
    function in the net/core/sock.c. The possibility of
    local escalation of privileges cannot be fully ruled out
    for a local unprivileged attacker. (CVE-2018-9568)

    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.

"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."

    descriptionThe SUSE Linux Enterprise 12 SP1 LTSS kernel was updated to receive various security and bugfixes. Four new speculative execution information leak issues have been identified in Intel CPUs. (bsc#1111331) CVE-2018-12126: Microarchitectural Store Buffer Data Sampling (MSBDS) CVE-2018-12127: Microarchitectural Fill Buffer Data Sampling (MFBDS) CVE-2018-12130: Microarchitectural Load Port Data Samling (MLPDS) CVE-2019-11091: Microarchitectural Data Sampling Uncacheable Memory (MDSUM) This kernel update contains software mitigations for these issues, which also utilize CPU microcode updates shipped in parallel. For more information on this set of information leaks, check out https://www.suse.com/support/kb/doc/?id=7023736 The following security bugs were fixed: CVE-2016-10741: fs/xfs/xfs_aops.c allowed local users to cause a denial of service (system crash) because there is a race condition between direct and memory-mapped I/O (associated with a hole) that is handled with BUG_ON instead of an I/O failure (bnc#1114920 bnc#1124010). CVE-2017-1000407: By flooding the diagnostic port 0x80 an exception can be triggered leading to a kernel panic (bnc#1071021). CVE-2017-16533: The usbhid_parse function in drivers/hid/usbhid/hid-core.c 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#1066674). CVE-2017-7273: The cp_report_fixup function in drivers/hid/hid-cypress.c allowed physically proximate attackers to cause a denial of service (integer underflow) or possibly have unspecified other impact via a crafted HID report (bnc#1031240). CVE-2017-7472: The KEYS subsystem 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-2018-14633: A security flaw was found in the chap_server_compute_md5() function in the ISCSI target code in the Linux kernel in a way an authentication request from an ISCSI initiator is processed. An unauthenticated remote attacker can cause a stack buffer overflow and smash up to 17 bytes of the stack. The attack requires the iSCSI target to be enabled on the victim host.

  • NASL familySuSE Local Security Checks
    NASL idSUSE_SU-2019-13937-1.NASL
    descriptionThe SUSE Linux Enterprise 12 SP3 kernel was updated to 3.0.101 to receive various security and bugfixes. The following security bugs were fixed : CVE-2018-9516: In hid_debug_events_read of drivers/hid/hid-debug.c, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation (bnc#1108498). CVE-2018-19407: The vcpu_scan_ioapic function in arch/x86/kvm/x86.c allowed local users to cause a denial of service (NULL pointer dereference and BUG) via crafted system calls that reach a situation where ioapic is uninitialized (bnc#1116841). CVE-2018-19985: The function hso_probe read if_num from the USB device (as an u8) and used it without a length check to index an array, resulting in an OOB memory read in hso_probe or hso_get_config_data that could be used by local attackers (bnc#1120743). CVE-2018-20169: The USB subsystem mishandled size checks during the reading of an extra descriptor, related to __usb_get_extra_descriptor in drivers/usb/core/usb.c (bnc#1119714). CVE-2018-9568: In sk_clone_lock of sock.c, there is a possible memory corruption due to type confusion. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation (bnc#1118319). CVE-2018-19824: A local user could exploit a use-after-free in the ALSA driver by supplying a malicious USB Sound device (with zero interfaces) that is mishandled in usb_audio_probe in sound/usb/card.c (bnc#1118152). CVE-2018-18281: The mremap() syscall performs TLB flushes after dropping pagetable locks. If a syscall such as ftruncate() removes entries from the pagetables of a task that is in the middle of mremap(), a stale TLB entry can remain for a short time that permits access to a physical page after it has been released back to the page allocator and reused (bnc#1113769). CVE-2018-18710: An information leak in cdrom_ioctl_select_disc in drivers/cdrom/cdrom.c could be used by local attackers to read kernel memory because a cast from unsigned long to int interferes with bounds checking. This is similar to CVE-2018-10940 and CVE-2018-16658 (bnc#1113751). CVE-2018-18386: drivers/tty/n_tty.c allowed local attackers (who are able to access pseudo terminals) to hang/block further usage of any pseudo terminal devices due to an EXTPROC versus ICANON confusion in TIOCINQ (bnc#1094825). CVE-2017-7273: The cp_report_fixup function in drivers/hid/hid-cypress.c allowed physically proximate attackers to cause a denial of service (integer underflow) or possibly have unspecified other impact via a crafted HID report (bnc#1031240). CVE-2017-16533: The usbhid_parse function in drivers/hid/usbhid/hid-core.c 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#1066674). CVE-2017-1000407: Fixed a denial of service, which was caused by flooding the diagnostic port 0x80 an exception leading to a kernel panic (bnc#1071021). The update package also includes non-security fixes. See advisory for details. Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    descriptionAccording 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 : - dccp_disconnect() set the socket state to DCCP_CLOSED but did not properly free some of the resources associated with that socket. This could result in a use-after-free and could potentially allow an attacker to escalate their privileges. - The Linux kernel is vulnerable to a use-after-free issue. It could occur while closing a xfrm netlink socket, in xfrm_dump_policy_done. A user/process could use this flaw to potentially escalate their privileges on a system. - A flaw was found in the patches used to fix the

    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

    descriptionThe remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has kernel-rt packages installed that are affected by multiple vulnerabilities: - Integer overflow in the aio_setup_single_vector function in fs/aio.c in the Linux kernel 4.0 allows local users to cause a denial of service or possibly have unspecified other impact via a large AIO iovec. NOTE: this vulnerability exists because of a CVE-2012-6701 regression. (CVE-2015-8830) - A weakness was found in the Linux ASLR implementation. Any user able to running 32-bit applications in a x86 machine can disable ASLR by setting the RLIMIT_STACK resource to unlimited. (CVE-2016-3672) - The xc2028_set_config function in drivers/media/tuners/tuner-xc2028.c in the Linux kernel before 4.6 allows local users to gain privileges or cause a denial of service (use-after-free) via vectors involving omission of the firmware name from a certain data structure. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely. (CVE-2016-7913) - Use-after-free vulnerability in the snd_pcm_info() function in the ALSA subsystem in the Linux kernel allows attackers to induce a kernel memory corruption and possibly crash or lock up a system. Due to the nature of the flaw, a privilege escalation cannot be fully ruled out, although we believe it is unlikely. (CVE-2017-0861) - A reachable assertion failure flaw was found in the Linux kernel built with KVM virtualisation(CONFIG_KVM) support with Virtual Function I/O feature (CONFIG_VFIO) enabled. This failure could occur if a malicious guest device sent a virtual interrupt (guest IRQ) with a larger (>1024) index value. (CVE-2017-1000252) - Linux kernel Virtualization Module (CONFIG_KVM) for the Intel processor family (CONFIG_KVM_INTEL) is vulnerable to a DoS issue. It could occur if a guest was to flood the I/O port 0x80 with write requests. A guest user could use this flaw to crash the host kernel resulting in DoS.

    descriptionThe SUSE Linux Enterprise 11 SP4 kernel was updated to 3.0.101-108.81 to receive various security and bugfixes. The following security bugs were fixed : CVE-2018-18281: An issue was discovered in the Linux kernel, the mremap() syscall performs TLB flushes after dropping pagetable locks. If a syscall such as ftruncate() removes entries from the pagetables of a task that is in the middle of mremap(), a stale TLB entry can remain for a short time that permits access to a physical page after it has been released back to the page allocator and reused (bnc#1113769). CVE-2018-18710: An issue was discovered in the Linux kernel, an information leak in cdrom_ioctl_select_disc in drivers/cdrom/cdrom.c could be used by local attackers to read kernel memory because a cast from unsigned long to int interferes with bounds checking. This is similar to CVE-2018-10940 and CVE-2018-16658 (bnc#1113751). CVE-2018-18386: drivers/tty/n_tty.c in the Linux kernel allowed local attackers (who are able to access pseudo terminals) to hang/block further usage of any pseudo terminal devices due to an EXTPROC versus ICANON confusion in TIOCINQ (bnc#1094825). CVE-2017-7273: The cp_report_fixup function in drivers/hid/hid-cypress.c in the Linux kernel 4.x allowed physically proximate attackers to cause a denial of service (integer underflow) or possibly have unspecified other impact via a crafted HID report (bnc#1031240). CVE-2017-16533: The usbhid_parse function in drivers/hid/usbhid/hid-core.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#1066674). CVE-2017-1000407: An denial of service issue was discovered in the Linux kernel, by flooding the diagnostic port 0x80 an exception can be triggered leading to a kernel panic (bnc#1071021). CVE-2018-9516: An issue was discovered in the Linux kernel, the copy_to_user() inside the HID code does not correctly check the length before executing (bsc#1108498). CVE-2018-14633: A security flaw was found in the chap_server_compute_md5() function in the ISCSI target code in the Linux kernel in a way an authentication request from an ISCSI initiator is processed.
