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
-------------------------------------------------------------------
1 app-text/ghostscript-gpl
< 9.20-r1 >= 9.20-r1

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 -v ">=app-text/ghostscript-gpl-9.20-r1"
