   An update that fixes two vulnerabilities is now available.

Description:

   This update for the Linux Kernel 3.12.55-52_42 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).
