SUSE SLES12 Security Update : kernel (SUSE-SU-2016:3247-1)

This script is Copyright (C) 2016-2017 Tenable Network Security, Inc.


Synopsis :

The remote SUSE host is missing one or more security updates.

Description :

This update for the Linux Kernel 3.12.60-52_57 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).

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
