SUSE SLED12 / SLES12 Security Update : ghostscript-library (SUSE-SU-2016:2492-1)

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 ghostscript-library fixes the following issues :

- Multiple security vulnerabilities have been discovered
where ghostscript's '-dsafer' flag did not provide
sufficient protection against unintended access to the
file system. Thus, a machine that would process a
specially crafted Postscript file would potentially leak
sensitive information to an attacker. (CVE-2013-5653,
bsc#1001951)

- An incorrect reference count was found in .setdevice.
This issue lead to a use-after-free scenario, which
could have been exploited for denial-of-service or,
possibly, arbitrary code execution attacks.
(CVE-2016-7978, bsc#1001951)

- Insufficient validation of the type of input in
.initialize_dsc_parser used to allow remote code
execution. (CVE-2016-7979, bsc#1001951)

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.
