This script is Copyright (C) 2016 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_49 fixes several issues.
The following security bugs were fixed :

- CVE-2016-4470: The key_reject_and_link function in
security/keys/key.c in the Linux kernel did not ensure
that a certain data structure is initialized, which
allowed local users to cause a denial of service (system
crash) via vectors involving a crafted keyctl request2
command (bsc#984764).

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.
