This update for the Linux Kernel 3.12.60-52_54 fixes several issues.
The following security bugs were fixed:
- CVE-2016-4470: The key_reject_and_link function in security/keys/key.c
in the Linux kernel did not ensure that a certain data structure is
initialized, which allowed local users to cause a denial of service
(system crash) via vectors involving a crafted keyctl request2 command
(bsc#984764).
