    Description:


    The SUSE Linux Enterprise Server 11 SP2 LTSS received a roll up update to
    fix several security and non-security issues.

    The following security issues have been fixed:

    * CVE-2014-0055: 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. (bnc#870173)
    * CVE-2014-0077: 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. (bnc#870576)
    * CVE-2014-1739: The media_device_enum_entities function in
    drivers/media/media-device.c in the Linux kernel before 3.14.6 does
    not initialize a certain data structure, which allows local users to
    obtain sensitive information from kernel memory by leveraging
    /dev/media0 read access for a MEDIA_IOC_ENUM_ENTITIES ioctl call.
    (bnc#882804)
    * CVE-2014-2706: Race condition in the mac80211 subsystem in the Linux
    kernel before 3.13.7 allows remote attackers to cause a denial of
    service (system crash) via network traffic that improperly interacts
    with the WLAN_STA_PS_STA state (aka power-save mode), related to
    sta_info.c and tx.c. (bnc#871797)
    * CVE-2014-2851: Integer overflow in the ping_init_sock function in
    net/ipv4/ping.c in the Linux kernel through 3.14.1 allows local
    users to cause a denial of service (use-after-free and system crash)
    or possibly gain privileges via a crafted application that leverages
    an improperly managed reference counter. (bnc#873374)
    * CVE-2014-3144: The (1) BPF_S_ANC_NLATTR and (2)
    BPF_S_ANC_NLATTR_NEST extension implementations in the sk_run_filter
    function in net/core/filter.c in the Linux kernel through 3.14.3 do
    not check whether a certain length value is sufficiently large,
    which allows local users to cause a denial of service (integer
    underflow and system crash) via crafted BPF instructions. NOTE: the
    affected code was moved to the __skb_get_nlattr and
    __skb_get_nlattr_nest functions before the vulnerability was
    announced. (bnc#877257)
    * CVE-2014-3145: The BPF_S_ANC_NLATTR_NEST extension implementation in
    the sk_run_filter function in net/core/filter.c in the Linux kernel
    through 3.14.3 uses the reverse order in a certain subtraction,
    which allows local users to cause a denial of service (over-read and
    system crash) via crafted BPF instructions. NOTE: the affected code
    was moved to the __skb_get_nlattr_nest function before the
    vulnerability was announced. (bnc#877257)
    * CVE-2014-3917: kernel/auditsc.c in the Linux kernel through 3.14.5,
    when CONFIG_AUDITSYSCALL is enabled with certain syscall rules,
    allows local users to obtain potentially sensitive single-bit values
    from kernel memory or cause a denial of service (OOPS) via a large
    value of a syscall number. (bnc#880484)
    * CVE-2014-4508: arch/x86/kernel/entry_32.S in the Linux kernel
    through 3.15.1 on 32-bit x86 platforms, when syscall auditing is
    enabled and the sep CPU feature flag is set, allows local users to
    cause a denial
    of service (OOPS and system crash) via an invalid syscall number, as
    demonstrated by number 1000. (bnc#883724)
    * CVE-2014-4652: Race condition in the tlv handler functionality in
    the snd_ctl_elem_user_tlv function in sound/core/control.c in the
    ALSA control implementation in the Linux kernel before 3.15.2 allows
    local users to obtain sensitive information from kernel memory by
    leveraging /dev/snd/controlCX access. (bnc#883795)
    * CVE-2014-4653: sound/core/control.c in the ALSA control
    implementation in the Linux kernel before 3.15.2 does not ensure
    possession of a read/write lock, which allows local users to cause a
    denial of service (use-after-free) and obtain sensitive information
    from kernel memory by leveraging /dev/snd/controlCX access.
    (bnc#883795)
    * CVE-2014-4654: The snd_ctl_elem_add function in sound/core/control.c
    in the ALSA control implementation in the Linux kernel before 3.15.2
    does not check authorization for SNDRV_CTL_IOCTL_ELEM_REPLACE
    commands, which allows local users to remove kernel controls and
    cause a denial of service (use-after-free and system crash) by
    leveraging /dev/snd/controlCX access for an ioctl call. (bnc#883795)
    * CVE-2014-4655: The snd_ctl_elem_add function in sound/core/control.c
    in the ALSA control implementation in the Linux kernel before 3.15.2
    does not properly maintain the user_ctl_count value, which allows
    local users to cause a denial of service (integer overflow and limit
    bypass) by leveraging /dev/snd/controlCX access for a large number
    of SNDRV_CTL_IOCTL_ELEM_REPLACE ioctl calls. (bnc#883795)
    * CVE-2014-4656: Multiple integer overflows in sound/core/control.c in
    the ALSA control implementation in the Linux kernel before 3.15.2
    allow local users to cause a denial of service by leveraging
    /dev/snd/controlCX access, related to (1) index values in the
    snd_ctl_add function and (2) numid values in the
    snd_ctl_remove_numid_conflict function. (bnc#883795)
    * CVE-2014-4667: The sctp_association_free function in
    net/sctp/associola.c in the Linux kernel before 3.15.2 does not
    properly manage a certain backlog value, which allows remote
    attackers to cause a denial of service (socket outage) via a crafted
    SCTP packet. (bnc#885422)
    * CVE-2014-4699: The Linux kernel before 3.15.4 on Intel processors
    does not properly restrict use of a non-canonical value for the
    saved RIP address in the case of a system call that does not use
    IRET, which allows local users to leverage a race condition and gain
    privileges, or cause a denial of service (double fault), via a
    crafted application that makes ptrace and fork system calls.
    (bnc#885725)
    * CVE-2014-5077: The sctp_assoc_update function in
    net/sctp/associola.c in the Linux kernel through 3.15.8, when SCTP
    authentication is enabled, allows remote attackers to cause a denial
    of service (NULL pointer dereference and OOPS) by starting to
    establish an association between two endpoints immediately after an
    exchange of INIT and INIT ACK chunks to establish an earlier
    association between these endpoints in the opposite direction.
    (bnc#889173)
    * CVE-2013-4299: Interpretation conflict in
    drivers/md/dm-snap-persistent.c in the Linux kernel through 3.11.6
    allows remote authenticated users to obtain sensitive information or
    modify data via a crafted mapping to a snapshot block device.
    (bnc#846404)

    nfs4_async_handle_error (bnc#889324).
    * NFS: Do not lose sockets when nfsd shutdown races with connection
    timeout (bnc#871854).
