An update that fixes two vulnerabilities is now available.

 

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).
