   An update that fixes two vulnerabilities is now available.

Description:

   This update for the Linux Kernel 3.12.49-11 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-2016-8666: The IP stack in the Linux kernel allowed remote attackers
     to cause a denial of service (stack consumption and panic) or possibly
     have unspecified other impact by triggering use of the GRO path for
     packets with tunnel stacking, as demonstrated by interleaved IPv4
     headers and GRE headers, a related issue to CVE-2016-7039 (bsc#1001487).
