Description:

 

This update for the Linux Kernel 3.12.62-60_62 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).
