   An update that fixes two vulnerabilities is now available.

Description:

   This update for the Linux Kernel 3.12.67-60_64_18 fixes several issues.

   The following security bugs were fixed:
   - CVE-2016-8655: A race condition in the af_packet packet_set_ring
     function could be used by local attackers to crash the kernel or gain
     privileges (bsc#1012759).
   - CVE-2016-9555: The sctp_sf_ootb function in net/sctp/sm_statefuns.c in
     the Linux kernel lacks chunk-length checking for the first chunk, which
     allowed remote attackers to cause a denial of service (out-of-bounds
     slab access) or possibly have unspecified other impact via crafted SCTP
     data (bsc#1012183).
