    descriptionThe openSUSE Leap 42.2 kernel was updated to 4.4.87 to receive various security and bugfixes. The following security bugs were fixed : - CVE-2017-1000251: The native Bluetooth stack in the Linux Kernel (BlueZ) was vulnerable to a stack overflow vulnerability in the processing of L2CAP configuration responses resulting in Remote code execution in kernel space (bnc#1057389). - 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-2017-11472: The acpi_ns_terminate() function in drivers/acpi/acpica/nsutils.c in the Linux kernel did not flush the operand cache and causes a kernel stack dump, which allowed local users to obtain sensitive information from kernel memory and bypass the KASLR protection mechanism (in the kernel through 4.9) via a crafted ACPI table (bnc#1049580). - CVE-2017-14051: An integer overflow in the qla2x00_sysfs_write_optrom_ctl function in drivers/scsi/qla2xxx/qla_attr.c in the Linux kernel allowed local users to cause a denial of service (memory corruption and system crash) by leveraging root access (bnc#1056588). - CVE-2017-12134: The xen_biovec_phys_mergeable function in drivers/xen/biomerge.c in Xen might allow local OS guest users to corrupt block device data streams and consequently obtain sensitive memory information, cause a denial of service, or gain host OS privileges by leveraging incorrect block IO merge-ability calculation (bnc#1051790 1053919). The following non-security bugs were fixed : - acpi / scan: Prefer devices without _HID for _ADR matching (git-fixes). - alsa: hda - Add stereo mic quirk for Lenovo G50-70 (17aa:3978) (bsc#1020657). - alsa: hda - Implement mic-mute LED mode enum (bsc#1055013). - alsa: hda/realtek - Add support headphone Mic for ALC221 of HP platform (bsc#1024405). - alsa: ice1712: Add support for STAudio ADCIII (bsc#1048934). - alsa: usb-audio: Apply sample rate quirk to Sennheiser headset (bsc#1052580). - Add

"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
details.

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

  - CVE-2017-7518
    Andy Lutomirski discovered that KVM is prone to an
    incorrect debug exception (#DB) error occurring while
    emulating a syscall instruction. A process inside a
    guest can take advantage of this flaw for privilege
    escalation inside a guest.

  - CVE-2017-7558 (stretch only)
    Stefano Brivio of Red Hat discovered that the SCTP
    subsystem is prone to a data leak vulnerability due to
    an out-of-bounds read flaw, allowing to leak up to 100
    uninitialized bytes to userspace.

  - CVE-2017-10661 (jessie only)
    Dmitry Vyukov of Google reported that the timerfd
    facility does not properly handle certain concurrent
    operations on a single file descriptor. This allows a
    local attacker to cause a denial of service or
    potentially execute arbitrary code.

  - CVE-2017-11600
    Bo Zhang reported that the xfrm subsystem does not
    properly validate one of the parameters to a netlink
    message. Local users with the CAP_NET_ADMIN capability
    can use this to cause a denial of service or potentially
    to execute arbitrary code.

  - CVE-2017-12134 / #866511 / XSA-229
    Jan H. Schoenherr of Amazon discovered that when Linux
    is running in a Xen PV domain on an x86 system, it may
    incorrectly merge block I/O requests. A buggy or
    malicious guest may trigger this bug in dom0 or a PV
    driver domain, causing a denial of service or
    potentially execution of arbitrary code.

  This issue can be mitigated by disabling merges on the underlying
  back-end block devices, e.g.:echo 2 >
  /sys/block/nvme0n1/queue/nomerges

  - CVE-2017-12146 (stretch only)
    Adrian Salido of Google reported a race condition in
    access to the'driver_override' attribute for platform
    devices in sysfs. If unprivileged users are permitted to
    access this attribute, this might allow them to gain
    privileges.

  - CVE-2017-12153
    Bo Zhang reported that the cfg80211 (wifi) subsystem
    does not properly validate the parameters to a netlink
    message. Local users with the CAP_NET_ADMIN capability
    (in any user namespace with a wifi device) can use this
    to cause a denial of service.

  - CVE-2017-12154
    Jim Mattson of Google reported that the KVM
    implementation for Intel x86 processors did not
    correctly handle certain nested hypervisor
    configurations. A malicious guest (or nested guest in a
    suitable L1 hypervisor) could use this for denial of
    service.

  - CVE-2017-14106
    Andrey Konovalov discovered that a user-triggerable
    division by zero in the tcp_disconnect() function could
    result in local denial of service.

  - CVE-2017-14140
    Otto Ebeling reported that the move_pages() system call
    performed insufficient validation of the UIDs of the
    calling and target processes, resulting in a partial
    ASLR bypass. This made it easier for local users to
    exploit vulnerabilities in programs installed with the
    set-UID permission bit set.

  - CVE-2017-14156
    'sohu0106' reported an information leak in the atyfb
    video driver. A local user with access to a framebuffer
    device handled by this driver could use this to obtain
    sensitive information.

  - CVE-2017-14340
    Richard Wareing discovered that the XFS implementation
    allows the creation of files with the 'realtime' flag on
    a filesystem with no realtime device, which can result
    in a crash (oops). A local user with access to an XFS
    filesystem that does not have a realtime device can use
    this for denial of service.

  - CVE-2017-14489
    ChunYu Wang of Red Hat discovered that the iSCSI
    subsystem does not properly validate the length of a
    netlink message, leading to memory corruption. A local
    user with permission to manage iSCSI devices can use
    this for denial of service or possibly to execute
    arbitrary code.

  - CVE-2017-14497 (stretch only)
    Benjamin Poirier of SUSE reported that vnet headers are
    not properly handled within the tpacket_rcv() function
    in the raw packet (af_packet) feature. A local user with
    the CAP_NET_RAW capability can take advantage of this
    flaw to cause a denial of service (buffer overflow, and
    disk and memory corruption) or have other impact.

  - CVE-2017-1000111
    Andrey Konovalov of Google reported a race condition in
    the raw packet (af_packet) feature. Local users with the
    CAP_NET_RAW capability can use this for denial of
    service or possibly to execute arbitrary code.

  - CVE-2017-1000112
    Andrey Konovalov of Google reported a race condition
    flaw in the UDP Fragmentation Offload (UFO) code. A
    local user can use this flaw for denial of service or
    possibly to execute arbitrary code.

  - CVE-2017-1000251 / #875881
    Armis Labs discovered that the Bluetooth subsystem does
    not properly validate L2CAP configuration responses,
    leading to a stack-based buffer overflow. This is one of
    several vulnerabilities dubbed 'Blueborne'. A nearby
    attacker can use this to cause a denial of service or
    possibly to execute arbitrary code on a system with
    Bluetooth enabled.

  - CVE-2017-1000252 (stretch only)
    Jan H. Schoenherr of Amazon reported that the KVM
    implementation for Intel x86 processors did not
    correctly validate interrupt injection requests. A local
    user with permission to use KVM could use this for
    denial of service.

  - CVE-2017-1000370
    The Qualys Research Labs reported that a large argument
    or environment list can result in ASLR bypass for 32-bit
    PIE binaries.

  - CVE-2017-1000371
    The Qualys Research Labs reported that a large argument
    or environment list can result in a stack/heap clash for
    32-bit PIE binaries.

  - CVE-2017-1000380
    Alexander Potapenko of Google reported a race condition
    in the ALSA (sound) timer driver, leading to an
    information leak. A local user with permission to access
    sound devices could use this to obtain sensitive
    information.

Debian disables unprivileged user namespaces by default, but if they
are enabled (via the kernel.unprivileged_userns_clone sysctl) then
CVE-2017-11600, CVE-2017-14497 and CVE-2017-1000111 can be exploited
by any local user."

    descriptionSecurity Fix(es) : - A race condition issue leading to a use-after-free flaw was found in the way the raw packet sockets are implemented in the Linux kernel networking subsystem handling synchronization. A local user able to open a raw packet socket (requires the CAP_NET_RAW capability) could use this flaw to elevate their privileges on the system. (CVE-2017-1000111, Important) - An exploitable memory corruption flaw was found in the Linux kernel. The append path can be erroneously switched from UFO to non-UFO in ip_ufo_append_data() when building an UFO packet with MSG_MORE option. If unprivileged user namespaces are available, this flaw can be exploited to gain root privileges. (CVE-2017-1000112, Important) - A divide-by-zero vulnerability was found in the __tcp_select_window function in the Linux kernel. This can result in a kernel panic causing a local denial of service. (CVE-2017-14106, Moderate) Bug Fix(es) : - When the operating system was booted with RHEV/oVirt, and the eh_deadline sysfs parameter was set to 10s, the Storage Area Network (SAN) issues caused eh_deadline to trigger with no handler. Consequently, a kernel panic occurred. This update fixes the lpfc driver, thus preventing the kernel panic under described circumstances. - When an NFS server returned the NFS4ERR_BAD_SEQID error to an OPEN request, the open-owner was removed from the state_owners rbtree. Consequently, NFS4 client infinite loop that required a reboot to recover occurred. This update changes NFS4ERR_BAD_SEQID handling to leave the open-owner in the state_owners rbtree by updating the create_time parameter so that it looks like a new open-owner. As a result, an NFS4 client is now able to recover without falling into the infinite recovery loop after receiving NFS4ERR_BAD_SEQID. - If an NFS client attempted to mount NFSv3 shares from an NFS server exported directly to the client

    handling synchronization. A local user able to open a
    raw packet socket (requires the CAP_NET_RAW capability)
    could use this flaw to elevate their privileges on the
    system. (CVE-2017-1000111, Important)

  - An exploitable memory corruption flaw was found in the
    Linux kernel. The append path can be erroneously
    switched from UFO to non-UFO in ip_ufo_append_data()
    when building an UFO packet with MSG_MORE option. If
    unprivileged user namespaces are available, this flaw
    can be exploited to gain root privileges.
    (CVE-2017-1000112, Important)

  - A divide-by-zero vulnerability was found in the
    __tcp_select_window function in the Linux kernel. This
    can result in a kernel panic causing a local denial of
    service. (CVE-2017-14106, Moderate)

Bug Fix(es) :

  - When the operating system was booted with RHEV/oVirt,
    and the eh_deadline sysfs parameter was set to 10s, the
    Storage Area Network (SAN) issues caused eh_deadline to
    trigger with no handler. Consequently, a kernel panic
    occurred. This update fixes the lpfc driver, thus
    preventing the kernel panic under described
    circumstances.

  - When an NFS server returned the NFS4ERR_BAD_SEQID error
    to an OPEN request, the open-owner was removed from the
    state_owners rbtree. Consequently, NFS4 client infinite
    loop that required a reboot to recover occurred. This
    update changes NFS4ERR_BAD_SEQID handling to leave the
    open-owner in the state_owners rbtree by updating the
    create_time parameter so that it looks like a new
    open-owner. As a result, an NFS4 client is now able to
    recover without falling into the infinite recovery loop
    after receiving NFS4ERR_BAD_SEQID.

  - If an NFS client attempted to mount NFSv3 shares from an
    NFS server exported directly to the client's IP address,
    and this NFS client had already mounted other shares
    that originated from the same server but were exported
    to the subnetwork which this client was part of, the
    auth.unix.ip cache expiration was not handled correctly.
    Consequently, the client received the 'stale file
    handle' errors when trying to mount the share. This
    update fixes handling of the cache expiration, and the
    NFSv3 shares now mount as expected without producing the
    'stale file handle' errors.

  - When running a script that raised the tx ring count to
    its maximum value supported by the Solarflare Network
    Interface Controller (NIC) driver, the EF10 family NICs
    allowed the settings exceeding the hardware's
    capability. Consequently, the Solarflare hardware became
    unusable with Scientific Linux 6. This update fixes the
    sfc driver, so that the tx ring can have maximum 2048
    entries for all EF10 NICs. As a result, the Solarflare
    hardware no longer becomes unusable."

    descriptionThe SUSE Linux Enterprise 12 SP3 kernel was updated to 4.4.92 to receive various security and bugfixes. The following security bugs were fixed : - CVE-2017-1000252: The KVM subsystem in the Linux kernel allowed guest OS users to cause a denial of service (assertion failure, and hypervisor hang or crash) via an out-of bounds guest_irq value, related to arch/x86/kvm/vmx.c and virt/kvm/eventfd.c (bnc#1058038). - CVE-2017-11472: The acpi_ns_terminate() function in drivers/acpi/acpica/nsutils.c in the Linux kernel did not flush the operand cache and causes a kernel stack dump, which allowed local users to obtain sensitive information from kernel memory and bypass the KASLR protection mechanism (in the kernel through 4.9) via a crafted ACPI table (bnc#1049580). - CVE-2017-12134: The xen_biovec_phys_mergeable function in drivers/xen/biomerge.c in Xen might allow local OS guest users to corrupt block device data streams and consequently obtain sensitive memory information, cause a denial of service, or gain host OS privileges by leveraging incorrect block IO merge-ability calculation (bnc#1051790 bsc#1053919). - CVE-2017-12153: A security flaw was discovered in the nl80211_set_rekey_data() function in net/wireless/nl80211.c in the Linux kernel This function did not check whether the required attributes are present in a Netlink request. This request can be issued by a user with the CAP_NET_ADMIN capability and may result in a NULL pointer dereference and system crash (bnc#1058410). - CVE-2017-12154: The prepare_vmcs02 function in arch/x86/kvm/vmx.c in the Linux kernel did not ensure that the

"The SUSE Linux Enterprise 12 SP3 kernel was updated to 4.4.92 to
receive various security and bugfixes. The following security bugs
were fixed :

  - CVE-2017-1000252: The KVM subsystem in the Linux kernel
    allowed guest OS users to cause a denial of service
    (assertion failure, and hypervisor hang or crash) via an
    out-of bounds guest_irq value, related to
    arch/x86/kvm/vmx.c and virt/kvm/eventfd.c (bnc#1058038).

  - CVE-2017-11472: The acpi_ns_terminate() function in
    drivers/acpi/acpica/nsutils.c in the Linux kernel did
    not flush the operand cache and causes a kernel stack
    dump, which allowed local users to obtain sensitive
    information from kernel memory and bypass the KASLR
    protection mechanism (in the kernel through 4.9) via a
    crafted ACPI table (bnc#1049580).

  - CVE-2017-12134: The xen_biovec_phys_mergeable function
    in drivers/xen/biomerge.c in Xen might allow local OS
    guest users to corrupt block device data streams and
    consequently obtain sensitive memory information, cause
    a denial of service, or gain host OS privileges by
    leveraging incorrect block IO merge-ability calculation
    (bnc#1051790 bsc#1053919).

  - CVE-2017-12153: A security flaw was discovered in the
    nl80211_set_rekey_data() function in
    net/wireless/nl80211.c in the Linux kernel This function
    did not check whether the required attributes are
    present in a Netlink request. This request can be issued
    by a user with the CAP_NET_ADMIN capability and may
    result in a NULL pointer dereference and system crash
    (bnc#1058410).

  - CVE-2017-12154: The prepare_vmcs02 function in
    arch/x86/kvm/vmx.c in the Linux kernel did not ensure
    that the 'CR8-load exiting' and 'CR8-store exiting' L0
    vmcs02 controls exist in cases where L1 omits the 'use
    TPR shadow' vmcs12 control, which allowed KVM L2 guest
    OS users to obtain read and write access to the hardware
    CR8 register (bnc#1058507).

  - 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
    within radio range to replay frames from access points
    to clients (bnc#1056061 1063479 1063667 1063671).

  - CVE-2017-14051: An integer overflow in the
    qla2x00_sysfs_write_optrom_ctl function in
    drivers/scsi/qla2xxx/qla_attr.c in the Linux kernel
    allowed local users to cause a denial of service (memory
    corruption and system crash) by leveraging root access
    (bnc#1056588).

  - 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-2017-14489: The iscsi_if_rx function in
    drivers/scsi/scsi_transport_iscsi.c in the Linux kernel
    allowed local users to cause a denial of service (panic)
    by leveraging incorrect length validation (bnc#1059051).

  - CVE-2017-15265: Use-after-free vulnerability in the
    Linux kernel before 4.14-rc5 allowed local users to have
    unspecified impact via vectors related to /dev/snd/seq
    (bnc#1062520).

  - CVE-2017-15649: net/packet/af_packet.c in the Linux
    kernel allowed local users to gain privileges via
    crafted system calls that trigger mishandling of
    packet_fanout data structures, because of a race
    condition (involving fanout_add and packet_do_bind) that
    leads to a use-after-free, a different vulnerability
    than CVE-2017-6346 (bnc#1064388).

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

description block directly from the SUSE security advisory. Tenable

"An update for kernel-rt is now available for Red Hat Enterprise MRG 2.

Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

The kernel-rt packages provide the Real Time Linux Kernel, which
enables fine-tuning for systems with extremely high determinism
requirements.

Security Fix(es) :

* Out-of-bounds kernel heap access vulnerability was found in xfrm,
kernel's IP framework for transforming packets. An error dealing with
netlink messages from an unprivileged user leads to arbitrary
read/write and privilege escalation. (CVE-2017-7184, Important)

* A race condition issue leading to a use-after-free flaw was found in
the way the raw packet sockets are implemented in the Linux kernel
networking subsystem handling synchronization. A local user able to
open a raw packet socket (requires the CAP_NET_RAW capability) could
use this flaw to elevate their privileges on the system.
(CVE-2017-1000111, Important)

* An exploitable memory corruption flaw was found in the Linux kernel.
The append path can be erroneously switched from UFO to non-UFO in
ip_ufo_append_data() when building an UFO packet with MSG_MORE option.
If unprivileged user namespaces are available, this flaw can be
exploited to gain root privileges. (CVE-2017-1000112, Important)

* Kernel memory corruption due to a buffer overflow was found in
brcmf_cfg80211_mgmt_tx() function in Linux kernels from v3.9-rc1 to
v4.13-rc1. The vulnerability can be triggered by sending a crafted
NL80211_CMD_FRAME packet via netlink. This flaw is unlikely to be
triggered remotely as certain userspace code is needed for this. An
unprivileged local user could use this flaw 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
unlikely. (CVE-2017-7541, Moderate)

* An integer overflow vulnerability in ip6_find_1stfragopt() function
was found. A local attacker that has privileges (of CAP_NET_RAW) to
open raw socket can cause an infinite loop inside the
ip6_find_1stfragopt() function. (CVE-2017-7542, Moderate)

* A kernel data leak due to an out-of-bound read was found in the
Linux kernel in inet_diag_msg_sctp{,l}addr_fill() and
sctp_get_sctp_info() functions present since version 4.7-rc1 through
version 4.13. A data leak happens when these functions fill in
sockaddr data structures used to export socket's diagnostic
information. As a result, up to 100 bytes of the slab data could be
leaked to a userspace. (CVE-2017-7558, Moderate)

* The mq_notify function in the Linux kernel through 4.11.9 does not
set the sock pointer to NULL upon entry into the retry logic. During a
user-space close of a Netlink socket, it allows attackers to possibly
cause a situation where a value may be used after being freed
(use-after-free) which may lead to memory corruption or other
unspecified other impact. (CVE-2017-11176, Moderate)

* A divide-by-zero vulnerability was found in the __tcp_select_window
function in the Linux kernel. This can result in a kernel panic
causing a local denial of service. (CVE-2017-14106, Moderate)

* A flaw was found where the XFS filesystem code mishandles a
user-settable inode flag in the Linux kernel prior to 4.14-rc1. This
can cause a local denial of service via a kernel panic.
(CVE-2017-14340, Moderate)

Red Hat would like to thank Chaitin Security Research Lab for
reporting CVE-2017-7184; Willem de Bruijn for reporting
CVE-2017-1000111; and Andrey Konovalov for reporting CVE-2017-1000112.
The CVE-2017-7558 issue was discovered by Stefano Brivio (Red Hat) and
the CVE-2017-14340 issue was discovered by Dave Chinner (Red Hat).

Bug Fix(es) :

* kernel-rt packages have been upgraded to the 3.10.0-693.5.2 source
tree, which provides number of bug fixes over the previous version.

"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

  - 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).

  - 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 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

"From Red Hat Security Advisory 2017:2930 :

An update for kernel is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

Security Fix(es) :

* Out-of-bounds kernel heap access vulnerability was found in xfrm,
kernel's IP framework for transforming packets. An error dealing with
netlink messages from an unprivileged user leads to arbitrary
read/write and privilege escalation. (CVE-2017-7184, Important)

* A race condition issue leading to a use-after-free flaw was found in
the way the raw packet sockets are implemented in the Linux kernel
networking subsystem handling synchronization. A local user able to
open a raw packet socket (requires the CAP_NET_RAW capability) could
use this flaw to elevate their privileges on the system.
(CVE-2017-1000111, Important)

* An exploitable memory corruption flaw was found in the Linux kernel.
The append path can be erroneously switched from UFO to non-UFO in
ip_ufo_append_data() when building an UFO packet with MSG_MORE option.
If unprivileged user namespaces are available, this flaw can be
exploited to gain root privileges. (CVE-2017-1000112, Important)

* A flaw was found in the Linux networking subsystem where a local
attacker with CAP_NET_ADMIN capabilities could cause an out-of-bounds
memory access by creating a smaller-than-expected ICMP header and
sending to its destination via sendto(). (CVE-2016-8399, Moderate)

* Kernel memory corruption due to a buffer overflow was found in
brcmf_cfg80211_mgmt_tx() function in Linux kernels from v3.9-rc1 to
v4.13-rc1. The vulnerability can be triggered by sending a crafted
NL80211_CMD_FRAME packet via netlink. This flaw is unlikely to be
triggered remotely as certain userspace code is needed for this. An
unprivileged local user could use this flaw 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
unlikely. (CVE-2017-7541, Moderate)

* An integer overflow vulnerability in ip6_find_1stfragopt() function
was found. A local attacker that has privileges (of CAP_NET_RAW) to
open raw socket can cause an infinite loop inside the
ip6_find_1stfragopt() function. (CVE-2017-7542, Moderate)

* A kernel data leak due to an out-of-bound read was found in the
Linux kernel in inet_diag_msg_sctp{,l}addr_fill() and
sctp_get_sctp_info() functions present since version 4.7-rc1 through
version 4.13. A data leak happens when these functions fill in
sockaddr data structures used to export socket's diagnostic
information. As a result, up to 100 bytes of the slab data could be
leaked to a userspace. (CVE-2017-7558, Moderate)

* The mq_notify function in the Linux kernel through 4.11.9 does not
set the sock pointer to NULL upon entry into the retry logic. During a
user-space close of a Netlink socket, it allows attackers to possibly
cause a situation where a value may be used after being freed
(use-after-free) which may lead to memory corruption or other
unspecified other impact. (CVE-2017-11176, Moderate)

* A divide-by-zero vulnerability was found in the __tcp_select_window
function in the Linux kernel. This can result in a kernel panic
causing a local denial of service. (CVE-2017-14106, Moderate)

Red Hat would like to thank Chaitin Security Research Lab for
reporting CVE-2017-7184; Willem de Bruijn for reporting
CVE-2017-1000111; and Andrey Konovalov for reporting CVE-2017-1000112.
The CVE-2017-7558 issue was discovered by Stefano Brivio (Red Hat).

Red Hat would like to thank Willem de Bruijn for reporting

Bug Fix(es) :

* When the operating system was booted with Red Hat Enterprise
Virtualization, and the eh_deadline sysfs parameter was set to 10s,
the Storage Area Network (SAN) issues caused eh_deadline to trigger
with no handler. Consequently, a kernel panic occurred. This update
fixes the lpfc driver, thus preventing the kernel panic under
described circumstances. (BZ #1487220)

* When an NFS server returned the NFS4ERR_BAD_SEQID error to an OPEN
request, the open-owner was removed from the state_owners rbtree.
Consequently, NFS4 client infinite loop that required a reboot to
recover occurred. This update changes NFS4ERR_BAD_SEQID handling to
leave the open-owner in the state_owners rbtree by updating the
create_time parameter so that it looks like a new open-owner. As a
result, an NFS4 client is now able to recover without falling into the
infinite recovery loop after receiving NFS4ERR_BAD_SEQID. (BZ#1491123)

* If an NFS client attempted to mount NFSv3 shares from an NFS server
exported directly to the client's IP address, and this NFS client had
already mounted other shares that originated from the same server but
were exported to the subnetwork which this client was part of, the
auth.unix.ip cache expiration was not handled correctly. Consequently,
the client received the 'stale file handle' errors when trying to
mount the share. This update fixes handling of the cache expiration,
and the NFSv3 shares now mount as expected without producing the
'stale file handle' errors. (BZ #1497976)

* When running a script that raised the tx ring count to its maximum
value supported by the Solarflare Network Interface Controller (NIC)
driver, the EF10 family NICs allowed the settings exceeding the
hardware's capability. Consequently, the Solarflare hardware became
unusable with Red Hat Entepripse Linux 6. This update fixes the sfc
driver, so that the tx ring can have maximum 2048 entries for all EF10
NICs. As a result, the Solarflare hardware no longer becomes unusable
with Red Hat Entepripse Linux 6 due to this bug. (BZ#1498019)"

This can result in a kernel panic causing a local denial-of-service. Note that Tenable Network Security has extracted the preceding description block directly from the Virtuozzo security advisory.

Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each

The kernel packages contain the Linux kernel, the core of any Linux

If unprivileged user namespaces are available, this flaw can be
exploited to gain root privileges. (CVE-2017-1000112, Important)

* A divide-by-zero vulnerability was found in the __tcp_select_window
function in the Linux kernel. This can result in a kernel panic
causing a local denial of service. (CVE-2017-14106, Moderate)

Red Hat would like to thank Willem de Bruijn for reporting
CVE-2017-1000111 and Andrey Konovalov for reporting CVE-2017-1000112.

Bug Fix(es) :

* When the operating system was booted with Red Hat Enterprise
Virtualization, and the eh_deadline sysfs parameter was set to 10s,
the Storage Area Network (SAN) issues caused eh_deadline to trigger
with no handler. Consequently, a kernel panic occurred. This update
fixes the lpfc driver, thus preventing the kernel panic under
described circumstances. (BZ #1487220)

* When an NFS server returned the NFS4ERR_BAD_SEQID error to an OPEN
request, the open-owner was removed from the state_owners rbtree.
Consequently, NFS4 client infinite loop that required a reboot to
recover occurred. This update changes NFS4ERR_BAD_SEQID handling to
leave the open-owner in the state_owners rbtree by updating the
create_time parameter so that it looks like a new open-owner. As a
result, an NFS4 client is now able to recover without falling into the
infinite recovery loop after receiving NFS4ERR_BAD_SEQID. (BZ#1491123)

* If an NFS client attempted to mount NFSv3 shares from an NFS server
exported directly to the client's IP address, and this NFS client had
already mounted other shares that originated from the same server but
were exported to the subnetwork which this client was part of, the
auth.unix.ip cache expiration was not handled correctly. Consequently,
the client received the 'stale file handle' errors when trying to
mount the share. This update fixes handling of the cache expiration,
and the NFSv3 shares now mount as expected without producing the
'stale file handle' errors. (BZ #1497976)

* When running a script that raised the tx ring count to its maximum
value supported by the Solarflare Network Interface Controller (NIC)
driver, the EF10 family NICs allowed the settings exceeding the
hardware's capability. Consequently, the Solarflare hardware became
unusable with Red Hat Entepripse Linux 6. This update fixes the sfc
driver, so that the tx ring can have maximum 2048 entries for all EF10
NICs. As a result, the Solarflare hardware no longer becomes unusable
with Red Hat Entepripse Linux 6 due to this bug. (BZ#1498019)"

    descriptionSeveral vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks. CVE-2017-7482 Shi Lei discovered that RxRPC Kerberos 5 ticket handling code does not properly verify metadata, leading to information disclosure, denial of service or potentially execution of arbitrary code. CVE-2017-7542 An integer overflow vulnerability in the ip6_find_1stfragopt() function was found allowing a local attacker with privileges to open raw sockets to cause a denial of service. CVE-2017-7889 Tommi Rantala and Brad Spengler reported that the mm subsystem does not properly enforce the CONFIG_STRICT_DEVMEM protection mechanism, allowing a local attacker with access to /dev/mem to obtain sensitive information or potentially execute arbitrary code. CVE-2017-10661 Dmitry Vyukov of Google reported that the timerfd facility does not properly handle certain concurrent operations on a single file descriptor. This allows a local attacker to cause a denial of service or potentially to execute arbitrary code. CVE-2017-10911 / XSA-216 Anthony Perard of Citrix discovered an information leak flaw in Xen blkif response handling, allowing a malicious unprivileged guest to obtain sensitive information from the host or other guests. CVE-2017-11176 It was discovered that the mq_notify() function does not set the sock pointer to NULL upon entry into the retry logic. An attacker can take advantage of this flaw during a userspace close of a Netlink socket to cause a denial of service or potentially cause other impact. CVE-2017-11600 bo Zhang reported that the xfrm subsystem does not properly validate one of the parameters to a netlink message. Local users with the CAP_NET_ADMIN capability can use this to cause a denial of service or potentially to execute arbitrary code. CVE-2017-12134 / #866511 / XSA-229 Jan H. Sch&ouml;nherr of Amazon discovered that when Linux is running in a Xen PV domain on an x86 system, it may incorrectly merge block I/O requests. A buggy or malicious guest may trigger this bug in dom0 or a PV driver domain, causing a denial of service or potentially execution of arbitrary code. This issue can be mitigated by disabling merges on the underlying back-end block devices, e.g.: echo 2 > /sys/block/nvme0n1/queue/nomerges CVE-2017-12153 bo Zhang reported that the cfg80211 (wifi) subsystem does not properly validate the parameters to a netlink message. Local users with the CAP_NET_ADMIN capability on a system with a wifi device can use this to cause a denial of service. CVE-2017-12154 Jim Mattson of Google reported that the KVM implementation for Intel x86 processors did not correctly handle certain nested hypervisor configurations. A malicious guest (or nested guest in a suitable L1 hypervisor) could use this for denial of service. CVE-2017-14106 Andrey Konovalov of Google reported that a specific sequence of operations on a TCP socket could lead to division by zero. A local user could use this for denial of service. CVE-2017-14140 Otto Ebeling reported that the move_pages() system call permitted users to discover the memory layout of a set-UID process running under their real user-ID. This made it easier for local users to exploit vulnerabilities in programs installed with the set-UID permission bit set. CVE-2017-14156

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

CVE-2017-7482

Shi Lei discovered that RxRPC Kerberos 5 ticket handling code does not
properly verify metadata, leading to information disclosure, denial of
service or potentially execution of arbitrary code.

CVE-2017-7542

An integer overflow vulnerability in the ip6_find_1stfragopt()
function was found allowing a local attacker with privileges to open
raw sockets to cause a denial of service.

CVE-2017-7889

Tommi Rantala and Brad Spengler reported that the mm subsystem does
not properly enforce the CONFIG_STRICT_DEVMEM protection mechanism,
allowing a local attacker with access to /dev/mem to obtain sensitive
information or potentially execute arbitrary code.

CVE-2017-10661

Dmitry Vyukov of Google reported that the timerfd facility does not
properly handle certain concurrent operations on a single file
descriptor. This allows a local attacker to cause a denial of service
or potentially to execute arbitrary code.

CVE-2017-10911 / XSA-216

Anthony Perard of Citrix discovered an information leak flaw in Xen
blkif response handling, allowing a malicious unprivileged guest to
obtain sensitive information from the host or other guests.

CVE-2017-11176

It was discovered that the mq_notify() function does not set the sock
pointer to NULL upon entry into the retry logic. An attacker can take
advantage of this flaw during a userspace close of a Netlink socket to
cause a denial of service or potentially cause other impact.

CVE-2017-11600

bo Zhang reported that the xfrm subsystem does not properly validate
one of the parameters to a netlink message. Local users with the
CAP_NET_ADMIN capability can use this to cause a denial of service or
potentially to execute arbitrary code.

CVE-2017-12134 / #866511 / XSA-229

Jan H. Sch&ouml;nherr of Amazon discovered that when Linux is running
in a Xen PV domain on an x86 system, it may incorrectly merge block
I/O requests. A buggy or malicious guest may trigger this bug in dom0
or a PV driver domain, causing a denial of service or potentially
execution of arbitrary code.

This issue can be mitigated by disabling merges on the
underlying back-end block devices, e.g.: echo 2 >
/sys/block/nvme0n1/queue/nomerges

CVE-2017-12153

bo Zhang reported that the cfg80211 (wifi) subsystem does not properly
validate the parameters to a netlink message. Local users with the
CAP_NET_ADMIN capability on a system with a wifi device can use this
to cause a denial of service.

CVE-2017-12154

Jim Mattson of Google reported that the KVM implementation for Intel
x86 processors did not correctly handle certain nested hypervisor
configurations. A malicious guest (or nested guest in a suitable L1
hypervisor) could use this for denial of service.

CVE-2017-14106

Andrey Konovalov of Google reported that a specific sequence of
operations on a TCP socket could lead to division by zero. A local
user could use this for denial of service.

CVE-2017-14140

Otto Ebeling reported that the move_pages() system call permitted
users to discover the memory layout of a set-UID process running under
their real user-ID. This made it easier for local users to exploit
vulnerabilities in programs installed with the set-UID permission bit
set.

CVE-2017-14156

'sohu0106' reported an information leak in the atyfb video driver. A
local user with access to a framebuffer device handled by this driver
could use this to obtain sensitive information.

CVE-2017-14340

Richard Wareing discovered that the XFS implementation allows the
creation of files with the 'realtime' flag on a filesystem with no
realtime device, which can result in a crash (oops). A local user with
access to an XFS filesystem that does not have a realtime device can
use this for denial of service.

CVE-2017-14489

ChunYu of Red Hat discovered that the iSCSI subsystem does not
properly validate the length of a netlink message, leading to memory
corruption. A local user with permission to manage iSCSI devices can
use this for denial of service or possibly to execute arbitrary code.

CVE-2017-1000111

Andrey Konovalov of Google reported that a race condition in the raw
packet (af_packet) feature. Local users with the CAP_NET_RAW
capability can use this to cause a denial of service or possibly to
execute arbitrary code.

CVE-2017-1000251 / #875881

Armis Labs discovered that the Bluetooth subsystem does not properly
validate L2CAP configuration responses, leading to a stack buffer
overflow. This is one of several vulnerabilities dubbed 'Blueborne'. A
nearby attacker can use this to cause a denial of service or possibly
to execute arbitrary code on a system with Bluetooth enabled.

CVE-2017-1000363

Roee Hay reported that the lp driver does not properly bounds-check
passed arguments. This has no security impact in Debian.

CVE-2017-1000365

It was discovered that argument and environment pointers are not
properly taken into account by the size restrictions on arguments and
environmental strings passed through execve(). A local attacker can
take advantage of this flaw in conjunction with other flaws to execute
arbitrary code.

CVE-2017-1000380

Alexander Potapenko of Google reported a race condition in the ALSA
(sound) timer driver, leading to an information leak. A local user
with permission to access sound devices could use this to obtain
sensitive information.

For Debian 7 'Wheezy', these problems have been fixed in version
3.2.93-1. This version also includes bug fixes from upstream versions
up to and including 3.2.93.

For Debian 8 'Jessie', these problems have been fixed in version

"An update for kernel-rt is now available for Red Hat Enterprise Linux
7.

Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

The kernel-rt packages provide the Real Time Linux Kernel, which
enables fine-tuning for systems with extremely high determinism
requirements.

Security Fix(es) :

* Out-of-bounds kernel heap access vulnerability was found in xfrm,
kernel's IP framework for transforming packets. An error dealing with
netlink messages from an unprivileged user leads to arbitrary
read/write and privilege escalation. (CVE-2017-7184, Important)

* A race condition issue leading to a use-after-free flaw was found in
the way the raw packet sockets are implemented in the Linux kernel
networking subsystem handling synchronization. A local user able to
open a raw packet socket (requires the CAP_NET_RAW capability) could
use this flaw to elevate their privileges on the system.
(CVE-2017-1000111, Important)

* An exploitable memory corruption flaw was found in the Linux kernel.
The append path can be erroneously switched from UFO to non-UFO in
ip_ufo_append_data() when building an UFO packet with MSG_MORE option.
If unprivileged user namespaces are available, this flaw can be
exploited to gain root privileges. (CVE-2017-1000112, Important)

* A flaw was found in the Linux networking subsystem where a local
attacker with CAP_NET_ADMIN capabilities could cause an out-of-bounds
memory access by creating a smaller-than-expected ICMP header and
sending to its destination via sendto(). (CVE-2016-8399, Moderate)

* Kernel memory corruption due to a buffer overflow was found in
brcmf_cfg80211_mgmt_tx() function in Linux kernels from v3.9-rc1 to
v4.13-rc1. The vulnerability can be triggered by sending a crafted
NL80211_CMD_FRAME packet via netlink. This flaw is unlikely to be
triggered remotely as certain userspace code is needed for this. An
unprivileged local user could use this flaw 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
unlikely. (CVE-2017-7541, Moderate)

* An integer overflow vulnerability in ip6_find_1stfragopt() function
was found. A local attacker that has privileges (of CAP_NET_RAW) to
open raw socket can cause an infinite loop inside the
ip6_find_1stfragopt() function. (CVE-2017-7542, Moderate)

* A kernel data leak due to an out-of-bound read was found in the
Linux kernel in inet_diag_msg_sctp{,l}addr_fill() and
sctp_get_sctp_info() functions present since version 4.7-rc1 through
version 4.13. A data leak happens when these functions fill in
sockaddr data structures used to export socket's diagnostic
information. As a result, up to 100 bytes of the slab data could be
leaked to a userspace. (CVE-2017-7558, Moderate)

* The mq_notify function in the Linux kernel through 4.11.9 does not
set the sock pointer to NULL upon entry into the retry logic. During a
user-space close of a Netlink socket, it allows attackers to possibly
cause a situation where a value may be used after being freed
(use-after-free) which may lead to memory corruption or other
unspecified other impact. (CVE-2017-11176, Moderate)

* A divide-by-zero vulnerability was found in the __tcp_select_window
function in the Linux kernel. This can result in a kernel panic
causing a local denial of service. (CVE-2017-14106, Moderate)

Red Hat would like to thank Chaitin Security Research Lab for
reporting CVE-2017-7184; Willem de Bruijn for reporting
CVE-2017-1000111; and Andrey Konovalov for reporting CVE-2017-1000112.
The CVE-2017-7558 issue was discovered by Stefano Brivio (Red Hat).

Bug Fix(es) :

* The kernel-rt packages have been upgraded to the 3.10.0-693.5.2
source tree, which provides number of bug fixes over the previous
version. (BZ# 1489084)"

    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 integer overflow vulnerability in ip6_find_1stfragopt() function was found. A local attacker that has privileges (of CAP_NET_RAW) to open raw socket can cause an infinite loop inside the ip6_find_1stfragopt() function. - Race condition in fs/timerfd.c in the Linux kernel before 4.10.15 allows local users to gain privileges or cause a denial of service (list corruption or use-after-free) via simultaneous file-descriptor operations that leverage improper might_cancel queueing. - A race condition issue leading to a use-after-free flaw was found in the way the raw packet sockets are implemented in the Linux kernel networking subsystem handling synchronization. A local user able to open a raw packet socket (requires the CAP_NET_RAW capability) could use this flaw to elevate their privileges on the system. - Andrey Konovalov discovered a race condition in the UDP Fragmentation Offload (UFO) code in the Linux kernel. A local attacker could use this to cause a denial of service or execute arbitrary code. - Kernel memory corruption due to a buffer overflow was found in brcmf_cfg80211_mgmt_tx() function in Linux kernels from v3.9-rc1 to v4.13-rc1. The vulnerability can be triggered by sending a crafted NL80211_CMD_FRAME packet via netlink. This flaw is unlikely to be triggered remotely as certain userspace code is needed for this. An unprivileged local user could use this flaw 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 we believe it is unlikely. - The mq_notify function in the Linux kernel through 4.11.9 does not set the sock pointer to NULL upon entry into the retry logic. During a user-space close of a Netlink socket, it allows attackers to possibly cause a situation where a value may be used after being freed (use after free) which may lead to memory corruption or other unspecified other impact. - The tcp_disconnect function in net/ipv4/tcp.c in the Linux kernel before 4.12 allows 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. Note that Tenable Network Security has extracted the preceding description block directly from the Virtuozzo security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

"Security Fix(es) :

  - Out-of-bounds kernel heap access vulnerability was found
    in xfrm, kernel's IP framework for transforming packets.
    An error dealing with netlink messages from an
    unprivileged user leads to arbitrary read/write and
    privilege escalation. (CVE-2017-7184, Important)

  - A race condition issue leading to a use-after-free flaw
    was found in the way the raw packet sockets are
    implemented in the Linux kernel networking subsystem
    handling synchronization. A local user able to open a
    raw packet socket (requires the CAP_NET_RAW capability)
    could use this flaw to elevate their privileges on the
    system. (CVE-2017-1000111, Important)

  - An exploitable memory corruption flaw was found in the
    Linux kernel. The append path can be erroneously
    switched from UFO to non-UFO in ip_ufo_append_data()
    when building an UFO packet with MSG_MORE option. If
    unprivileged user namespaces are available, this flaw
    can be exploited to gain root privileges.
    (CVE-2017-1000112, Important)

  - A flaw was found in the Linux networking subsystem where
    a local attacker with CAP_NET_ADMIN capabilities could
    cause an out-of-bounds memory access by creating a
    smaller-than-expected ICMP header and sending to its
    destination via sendto(). (CVE-2016-8399, Moderate)

  - Kernel memory corruption due to a buffer overflow was
    found in brcmf_cfg80211_mgmt_tx() function in Linux
    kernels from v3.9-rc1 to v4.13-rc1. The vulnerability
    can be triggered by sending a crafted NL80211_CMD_FRAME
    packet via netlink. This flaw is unlikely to be
    triggered remotely as certain userspace code is needed
    for this. An unprivileged local user could use this flaw
    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 unlikely. (CVE-2017-7541, Moderate)

  - An integer overflow vulnerability in
    ip6_find_1stfragopt() function was found. A local
    attacker that has privileges (of CAP_NET_RAW) to open
    raw socket can cause an infinite loop inside the
    ip6_find_1stfragopt() function. (CVE-2017-7542,
    Moderate)

  - A kernel data leak due to an out-of-bound read was found
    in the Linux kernel in inet_diag_msg_sctp{,l}addr_fill()
    and sctp_get_sctp_info() functions present since version
    4.7-rc1 through version 4.13. A data leak happens when
    these functions fill in sockaddr data structures used to
    export socket's diagnostic information. As a result, up
    to 100 bytes of the slab data could be leaked to a
    userspace. (CVE-2017-7558, Moderate)

  - The mq_notify function in the Linux kernel through
    4.11.9 does not set the sock pointer to NULL upon entry
    into the retry logic. During a user- space close of a
    Netlink socket, it allows attackers to possibly cause a
    situation where a value may be used after being freed
    (use-after-free) which may lead to memory corruption or
    other unspecified other impact. (CVE-2017-11176,
    Moderate)

  - A divide-by-zero vulnerability was found in the
    __tcp_select_window function in the Linux kernel. This
    can result in a kernel panic causing a local denial of
    service. (CVE-2017-14106, Moderate)"

    descriptionUSN-3444-1 fixed vulnerabilities in the Linux kernel for Ubuntu 16.04 LTS. This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 16.04 LTS for Ubuntu 14.04 LTS. Jan H. Schonherr discovered that the Xen subsystem did not properly handle block IO merges correctly in some situations. An attacker in a guest vm could use this to cause a denial of service (host crash) or possibly gain administrative privileges in the host. (CVE-2017-12134) Andrey Konovalov discovered that a divide-by-zero error existed in the TCP stack implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2017-14106) Otto Ebeling discovered that the memory manager in the Linux kernel did not properly check the effective UID in some situations. A local attacker could use this to expose sensitive information. (CVE-2017-14140). 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.

(CVE-2013-7269) - The packet_recvmsg function in net/packet/af_packet.c in the Linux kernel before 3.12.4 updates a certain length value before ensuring that an associated data structure has been initialized, which allows local users to obtain sensitive information from kernel memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system call. (CVE-2013-7270) - The x25_recvmsg function in net/x25/af_x25.c in the Linux kernel before 3.12.4 updates a certain length value without ensuring that an associated data structure has been initialized, which allows local users to obtain sensitive information from kernel memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system call. (CVE-2013-7271) - Buffer overflow in the complete_emulated_mmio function in arch/x86/kvm/x86.c in the Linux kernel before 3.13.6 allows guest OS users to execute arbitrary code on the host OS by leveraging a loop that triggers an invalid memory copy affecting certain cancel_work_item data. (CVE-2014-0049) - The get_rx_bufs function in drivers/vhost/net.c in the vhost-net subsystem in the Linux kernel package before 2.6.32-431.11.2 on Red Hat Enterprise Linux (RHEL) 6 does not properly handle vhost_get_vq_desc errors, which allows guest OS users to cause a denial of service (host OS crash) via unspecified vectors. (CVE-2014-0055) - The cifs_iovec_write function in fs/cifs/file.c in the Linux kernel through 3.13.5 does not properly handle uncached write operations that copy fewer than the requested number of bytes, which allows local users to obtain sensitive information from kernel memory, cause a denial of service (memory corruption and system crash), or possibly gain privileges via a writev system call with a crafted pointer. (CVE-2014-0069) - drivers/vhost/net.c in the Linux kernel before 3.13.10, when mergeable buffers are disabled, does not properly validate packet lengths, which allows guest OS users to cause a denial of service (memory corruption and host OS crash) or possibly gain privileges on the host OS via crafted packets, related to the handle_rx and get_rx_bufs functions. (CVE-2014-0077) - Race condition in the inet_frag_intern function in net/ipv4/inet_fragment.c in the Linux kernel through 3.13.6 allows remote attackers to cause a denial of service (use-after-free error) or possibly have unspecified other impact via a large series of fragmented ICMP Echo Request packets to a system with a heavy CPU load. (CVE-2014-0100) - A flaw was found in the way the Linux kernel processed an authenticated COOKIE_ECHO chunk during the initialization of an SCTP connection. A remote attacker could use this flaw to crash the system by initiating a specially crafted SCTP handshake in order to trigger a NULL pointer dereference on the system. (CVE-2014-0101) - The keyring_detect_cycle_iterator function in security/keys/keyring.c in the Linux kernel through 3.13.6 does not properly determine whether keyrings are identical, which allows local users to cause a denial of service (OOPS) via crafted keyctl commands. (CVE-2014-0102) - Use-after-free vulnerability in the skb_segment function in net/core/skbuff.c in the Linux kernel through 3.13.6 allows attackers to obtain sensitive information from kernel memory by leveraging the absence of a certain orphaning operation.

(CVE-2014-1438) - The help function in net/netfilter/nf_nat_irc.c in the Linux kernel before 3.12.8 allows remote attackers to obtain sensitive information from kernel memory by establishing an IRC DCC session in which incorrect packet data is transmitted during use of the NAT mangle feature. (CVE-2014-1690) - The ip6_route_add function in net/ipv6/route.c in the Linux kernel through 3.13.6 does not properly count the addition of routes, which allows remote attackers to cause a denial of service (memory consumption) via a flood of ICMPv6 Router Advertisement packets. (CVE-2014-2309) - net/netfilter/nf_conntrack_proto_dccp.c in the Linux kernel through 3.13.6 uses a DCCP header pointer incorrectly, which allows remote attackers to cause a denial of service (system crash) or possibly execute arbitrary code via a DCCP packet that triggers a call to the (1) dccp_new, (2) dccp_packet, or (3) dccp_error function.

  • NASL familyCentOS Local Security Checks
    NASL idCENTOS_RHSA-2017-3200.NASL
    descriptionAn update for kernel is now available for Red Hat Enterprise Linux 6. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es) : * A race condition issue leading to a use-after-free flaw was found in the way the raw packet sockets are implemented in the Linux kernel networking subsystem handling synchronization. A local user able to open a raw packet socket (requires the CAP_NET_RAW capability) could use this flaw to elevate their privileges on the system. (CVE-2017-1000111, Important) * An exploitable memory corruption flaw was found in the Linux kernel. The append path can be erroneously switched from UFO to non-UFO in ip_ufo_append_data() when building an UFO packet with MSG_MORE option. If unprivileged user namespaces are available, this flaw can be exploited to gain root privileges. (CVE-2017-1000112, Important) * A divide-by-zero vulnerability was found in the __tcp_select_window function in the Linux kernel. This can result in a kernel panic causing a local denial of service. (CVE-2017-14106, Moderate) Red Hat would like to thank Willem de Bruijn for reporting CVE-2017-1000111 and Andrey Konovalov for reporting CVE-2017-1000112. Bug Fix(es) : * When the operating system was booted with Red Hat Enterprise Virtualization, and the eh_deadline sysfs parameter was set to 10s, the Storage Area Network (SAN) issues caused eh_deadline to trigger with no handler. Consequently, a kernel panic occurred. This update fixes the lpfc driver, thus preventing the kernel panic under described circumstances. (BZ #1487220) * When an NFS server returned the NFS4ERR_BAD_SEQID error to an OPEN request, the open-owner was removed from the state_owners rbtree. Consequently, NFS4 client infinite loop that required a reboot to recover occurred. This update changes NFS4ERR_BAD_SEQID handling to leave the open-owner in the state_owners rbtree by updating the create_time parameter so that it looks like a new open-owner. As a result, an NFS4 client is now able to recover without falling into the infinite recovery loop after receiving NFS4ERR_BAD_SEQID. (BZ#1491123) * If an NFS client attempted to mount NFSv3 shares from an NFS server exported directly to the client
