An update that solves two vulnerabilities can now be installed.

Description:

This update for the Linux Kernel 3.12.51-52_34 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#1004418). - 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#986362).
