SUSE SLED12 / SLES12 Security Update : kernel (SUSE-SU-2016:3049-1)

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

Synopsis :

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

Description :

The SUSE Linux Enterprise 12 SP2 kernel was updated to receive
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

- 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).

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.
