   An update that solves 9 vulnerabilities and has 54 fixes is
   now available.

Description:


   The SUSE Linux Enterprise 11 SP3 Realtime kernel was updated to receive
   various security and bugfixes.

   Following security bugs were fixed:
   - CVE-2015-8104: The KVM subsystem in the Linux kernel allowed guest OS
     users to cause a denial of service (host OS panic or hang) by triggering
     many #DB (aka Debug) exceptions, related to svm.c (bnc#954404).
   - CVE-2015-5307: The KVM subsystem in the Linux kernel allowed guest OS
     users to cause a denial of service (host OS panic or hang) by triggering
     many #AC (aka Alignment Check) exceptions, related to svm.c and vmx.c
     (bnc#953527).
   - CVE-2015-7990: RDS: Verify the underlying transport exists before
     creating a connection, preventing possible DoS (bsc#952384,
     CVE-2015-7990).
   - CVE-2015-5157: arch/x86/entry/entry_64.S in the Linux kernel on the
     x86_64 platform mishandled IRET faults in processing NMIs that
     occurred during userspace execution, which might allow local users to
      gain privileges by triggering an NMI (bnc#937969 bnc#937970 bnc#938706
      bnc#939207).
   - CVE-2015-7872: The key_gc_unused_keys function in security/keys/gc.c in
     the Linux kernel allowed local users to cause a denial of service (OOPS)
     via crafted keyctl commands (bnc#951440).
   - CVE-2015-8215: net/ipv6/addrconf.c in the IPv6 stack in the Linux kernel
     did not validate attempted changes to the MTU value, which allowed
     context-dependent attackers to cause a denial of service (packet loss)
     via a value that is (1) smaller than the minimum compliant value or (2)
     larger than the MTU of an interface, as demonstrated by a Router
     Advertisement (RA) message that is not validated by a daemon, a
     different vulnerability than CVE-2015-0272. NOTE: the scope of
     CVE-2015-0272 is limited to the NetworkManager product. (bnc#955354).
   - CVE-2015-6937: The __rds_conn_create function in net/rds/connection.c in
     the Linux kernel allowed local users to cause a denial of service (NULL
     pointer dereference and system crash) or possibly have unspecified
     other impact by using a socket that was not properly bound (bnc#945825).
   - CVE-2015-6252: The vhost_dev_ioctl function in drivers/vhost/vhost.c in
     the Linux kernel allowed local users to cause a denial of service
     (memory consumption) via a VHOST_SET_LOG_FD ioctl call that triggers
     permanent file-descriptor allocation (bnc#942367).
