   An update that solves three vulnerabilities and has four
   fixes is now available.

Description:



   The SUSE Linux Enterprise 11 SP4 kernel was updated to receive various
   security and bugfixes.

   The following security bugs were fixed:

   - CVE-2018-1087: And an unprivileged KVM guest user could use this flaw to
     potentially escalate their privileges inside a guest. (bsc#1087088)
   - CVE-2018-8897: An unprivileged system user could use incorrect set up
     interrupt stacks to crash the Linux kernel resulting in DoS issue.
     (bsc#1087088)
   - CVE-2018-10124: The kill_something_info function in kernel/signal.c in
     the Linux kernel before 4.13, when an unspecified architecture and
     compiler is used, might allow local users to cause a denial of service
     via an INT_MIN argument (bnc#1089752).

   The following non-security bugs were fixed:

   - kvm/x86: fix icebp instruction handling (bsc#1087088).
   - media: cpia2: Fix a couple off by one bugs (bsc#1050431).
   - nfs: add nostatflush mount option (bsc#1065726).
   - nfs: allow flush-on-stat to be disabled (bsc#1065726).
   - powerpc/fadump: Add a warning when 'fadump_reserve_mem=' is used
     (bnc#1032084, FATE#323225).
   - powerpc/fadump: reuse crashkernel parameter for fadump memory
     reservation (bnc#1032084, FATE#323225).
   - powerpc/fadump: update documentation about crashkernel parameter reuse
     (bnc#1032084, FATE#323225).
   - powerpc/fadump: use 'fadump_reserve_mem=' when specified (bnc#1032084,
     FATE#323225).
   - x86/entry/64: Do not use IST entry for #BP stack (bsc#1087088).
