openSUSE-SU-2016:2574-1: important: Security update for ghostscript-library
openSUSE Security Update: Security update for ghostscript-library
______________________________________________________________________________

Announcement ID: openSUSE-SU-2016:2574-1
Rating: important
References: #1001951
Cross-References: CVE-2013-5653 CVE-2016-7978 CVE-2016-7979

Affected Products:
openSUSE Leap 42.1
______________________________________________________________________________

An update that fixes three vulnerabilities is now available.

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)

This update was imported from the SUSE:SLE-12:Update update project.
