This update for the Linux Kernel 3.12.55-52_42 fixes several issues.
The following security bugs were fixed: - CVE-2016-8655: A race condition in the afpacket packetsetring function could be used by local attackers to crash the kernel or gain privileges (bsc#1012759). - CVE-2016-9555: The sctpsfootb function in net/sctp/smstatefuns.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). - CVE-2016-7117: Use-after-free vulnerability in the _sysrecvmmsg function in net/socket.c in the Linux kernel allowed remote attackers to execute arbitrary code via vectors involving a recvmmsg system call that is mishandled during error processing (bsc#1003253).
