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).");
