Severity:	normal
Title:	GPL Ghostscript: Multiple vulnerabilities
Date:	02/22/2017
Bugs:	#596576, #607190
ID:	201702-31

Synopsis

Multiple vulnerabilities have been found in GPL Ghostscript, the worst of which may allow execution of arbitrary code.

Background

Ghostscript is an interpreter for the PostScript language and for PDF.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
app-text/ghostscript-gpl	< 9.20-r1	>= 9.20-r1	All supported architectures

Description

Multiple vulnerabilities have been discovered in GPL Ghostscript and the bundled OpenJPEG. Please review the CVE identifiers and GLSA-201612-26 (OpenJPEG) referenced below for additional information.

Note: GPL Ghostscript in Gentoo since app-text/ghostscript-gpl-9.20-r1 no longer bundles OpenJPEG.

Impact

A context-dependent attacker could entice a user to open a specially crafted PostScript file or PDF using GPL Ghostscript possibly resulting in the execution of arbitrary code with the privileges of the process or a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All GPL Ghostscript users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose
      ">=app-text/ghostscript-gpl-9.20-r1"
