Security update for the Linux Kernel
The SUSE Linux Enterprise 12 SP1 kernel was updated to receive various critical security fixes. 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#1012754). - CVE-2016-8632: The tipc_msg_build function in net/tipc/msg.c in the Linux kernel did not validate the relationship between the minimum fragment length and the maximum packet size, which allowed local users to gain privileges or cause a denial of service (heap-based buffer overflow) by leveraging the CAP_NET_ADMIN capability (bnc#1008831). - 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 (bnc#1011685).
