Synopsis: Moderate: ghostscript security update

Advisory ID: RHSA-2009:0421-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2009-0421.html

Issue date: 2009-04-14

CVE-2009-0792

=====================================================================

 

1. Summary:

 

Updated ghostscript packages that fix multiple security issues are now

available for Red Hat Enterprise Linux 5.

 

This update has been rated as having moderate security impact by the Red

Hat Security Response Team.

 

2. Relevant releases/architectures:

 

RHEL Desktop Workstation (v. 5 client) - i386, x86_64

Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64

Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64

 

3. Description:

 

Ghostscript is a set of software that provides a PostScript interpreter, a

set of C procedures (the Ghostscript library, which implements the graphics

capabilities in the PostScript language) and an interpreter for Portable

Document Format (PDF) files.

 

It was discovered that the Red Hat Security Advisory RHSA-2009:0345 did not

address all possible integer overflow flaws in Ghostscript's International

Color Consortium Format library (icclib). Using specially-crafted ICC

profiles, an attacker could create a malicious PostScript or PDF file with

embedded images that could cause Ghostscript to crash or, potentially,

execute arbitrary code when opened. (CVE-2009-0792)

 

A buffer overflow flaw and multiple missing boundary checks were found in

Ghostscript. An attacker could create a specially-crafted PostScript or PDF

file that could cause Ghostscript to crash or, potentially, execute

arbitrary code when opened. (CVE-2008-6679, CVE-2007-6725, CVE-2009-0196)

 

Red Hat would like to thank Alin Rad Pop of Secunia Research for

responsibly reporting the CVE-2009-0196 flaw.

 

Users of ghostscript are advised to upgrade to these updated packages,

which contain backported patches to correct these issues.

 

4. Solution:

 

Before applying this update, make sure that all previously-released

errata relevant to your system have been applied.
