Red Hat Security Advisory

Synopsis: Moderate: ghostscript security update
Advisory ID: RHSA-2017:0013-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2017-0013.html
Issue date: 2017-01-04
CVE Names: CVE-2013-5653 CVE-2016-7977 CVE-2016-7978
CVE-2016-7979 CVE-2016-8602
=====================================================================

1. Summary:

An update for ghostscript is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact
of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available for each vulnerability from
the CVE link(s) in the References section.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Client (v. 7) – x86_64
Red Hat Enterprise Linux Client Optional (v. 7) – noarch, x86_64
Red Hat Enterprise Linux ComputeNode (v. 7) – x86_64

Red Hat Enterprise Linux Workstation Optional (v. 7) – noarch, x86_64

3. Description:

The Ghostscript suite contains utilities for rendering PostScript and PDF
documents. Ghostscript translates PostScript code to common bitmap formats
so that the code can be displayed or printed.

Security Fix(es):

* It was found that the ghostscript functions getenv, filenameforall and
.libfile did not honor the -dSAFER option, usually used when processing
untrusted documents, leading to information disclosure. A specially crafted
postscript document could read environment variable, list directory and
retrieve file content respectively, from the target. (CVE-2013-5653,
CVE-2016-7977)

* It was found that the ghostscript function .setdevice suffered a
use-after-free vulnerability due to an incorrect reference count. A
specially crafted postscript document could trigger code execution in the
context of the gs process. (CVE-2016-7978)

* It was found that the ghostscript function .initialize_dsc_parser did not
validate its parameter before using it, allowing a type confusion flaw. A
specially crafted postscript document could cause a crash code execution in
the context of the gs process. (CVE-2016-7979)

* It was found that ghostscript did not sufficiently check the validity of
parameters given to the .sethalftone5 function. A specially crafted
postscript document could cause a crash, or execute arbitrary code in the
context of the gs process. (CVE-2016-8602)

4. Solution:

described in this advisory, refer to:
