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

critical Nessus Plugin ID 94006

Language:

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.
