SUSE SLES12 Security Update : kernel (SUSE-SU-2017:0866-1)

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


Synopsis :

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

Description :

The SUSE Linux Enterprise 12 kernel was updated to fix the following
security bugs :

- CVE-2017-7184: The Linux kernel allowed local users to
obtain root privileges or cause a denial of service
(heap-based out-of-bounds access) via unspecified
vectors, as demonstrated during a Pwn2Own competition at
CanSecWest 2017 (bnc#1030573, bnc#1028372).

- CVE-2017-2636: Race condition in drivers/tty/n_hdlc.c in
the Linux kernel allowed local users to gain privileges
or cause a denial of service (double free) by setting
the HDLC line discipline (bnc#1027565).

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.
