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 ComputeNode Optional (v. 7) - noarch, x86_64

Red Hat Enterprise Linux Server (v. 7) - aarch64, ppc64, ppc64le, s390x, x86_64

Red Hat Enterprise Linux Server Optional (v. 7) - aarch64, noarch, ppc64, ppc64le, s390x, x86_64

Red Hat Enterprise Linux Workstation (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:
