______________________________________________________________________________

   An update that solves 7 vulnerabilities and has 50 fixes is
   now available. It includes one version update.

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
   <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)
