    Description:


    The SUSE Linux Enterprise 11 Service Pack 3 RealTime
    Extension kernel has been updated to fix various bugs and
    security issues.

    ------------------------------------------------------------
    ------------ WARNING: If you are running KVM with PCI
    pass-through on a system with one of the following Intel
    chipsets: 5500 (revision 0x13), 5520 (revision 0x13) or
    X58 (revisions 0x12, 0x13, 0x22), please make sure to read
    the following support document before installing this
    update: https://www.suse.com/support/kb/doc.php?id=7014344
    You
    will have to update your KVM setup to no longer make use
    of PCI pass-through before rebooting to the updated
    kernel.
    ------------------------------------------------------------
    ------------

    The following security bugs have been fixed:

    *

    CVE-2013-4470: The Linux kernel before 3.12, when UDP
    Fragmentation Offload (UFO) is enabled, does not properly
    initialize certain data structures, which allows local
    users to cause a denial of service (memory corruption and
    system crash) or possibly gain privileges via a crafted
    application that uses the UDP_CORK option in a setsockopt
    system call and sends both short and long packets, related
    to the ip_ufo_append_data function in net/ipv4/ip_output.c
    and the ip6_ufo_append_data function in
    net/ipv6/ip6_output.c. (bnc#847672)

    *

    CVE-2013-6368: The KVM subsystem in the Linux kernel
    through 3.12.5 allows local users to gain privileges or
    cause a denial of service (system crash) via a VAPIC
    synchronization operation involving a page-end address.
    (bnc#853052)

    *

    CVE-2013-6885: The microcode on AMD 16h 00h through
    0Fh processors does not properly handle the interaction
    between locked instructions and write-combined memory
    types, which allows local users to cause a denial of
    service (system hang) via a crafted application, aka the
    errata 793 issue. (bnc#852967)

    *

    CVE-2013-7263: The Linux kernel before 3.12.4 updates
    certain length values before ensuring that associated data
    structures have been initialized, which allows local users
    to obtain sensitive information from kernel stack memory
    via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system
    call, related to net/ipv4/ping.c, net/ipv4/raw.c,
    net/ipv4/udp.c, net/ipv6/raw.c, and net/ipv6/udp.c.
    (bnc#857643)

    *

    CVE-2013-7264: The l2tp_ip_recvmsg function in
    net/l2tp/l2tp_ip.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 stack memory via a (1) recvfrom, (2) recvmmsg, or
    (3) recvmsg system call. (bnc#857643)

    *

    CVE-2013-7265: The pn_recvmsg function in
    net/phonet/datagram.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 stack memory via a (1) recvfrom, (2) recvmmsg, or
    (3) recvmsg system call. (bnc#857643)

    *

    CVE-2014-0069: 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. (bnc#864025)
