______________________________________________________________________________

 

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.
