An update that fixes three vulnerabilities is now available.
Description:
This update for the Linux Kernel 3.12.49-11 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).
- CVE-2016-7117: Use-after-free vulnerability in the __sys_recvmmsg
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).
