    Description:

    This update for the Linux Kernel 3.12.51-52_39 fixes several issues.

    The following security bugs were fixed:
    - CVE-2016-5195: A local privilege escalation using MAP_PRIVATE was fixed,
    which is reportedly exploited in the wild (bsc#1004419).
    - CVE-2016-4997: The compat IPT_SO_SET_REPLACE and IP6T_SO_SET_REPLACE
    setsockopt implementations in the netfilter subsystem in the Linux
    kernel allowed local users to gain privileges or cause a denial of
    service (memory corruption) by leveraging in-container root access to
    provide a crafted offset value that triggers an unintended decrement
    (bsc#986377).
