    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).
