CentOS 5 / 6 : ghostscript (CESA-2012:1256)

medium Nessus Plugin ID 62048

Language:

Synopsis

The remote CentOS host is missing one or more security updates.

Description

Updated ghostscript packages that fix one security issue are now available for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

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.

An integer overflow flaw, leading to a heap-based buffer overflow, was found in Ghostscript's International Color Consortium Format library (icclib). An attacker could create a specially crafted PostScript or PDF file with embedded images that would cause Ghostscript to crash or, potentially, execute arbitrary code with the privileges of the user running Ghostscript. (CVE-2012-4405)

Red Hat would like to thank Marc Schonefeld for reporting this issue.

Users of Ghostscript are advised to upgrade to these updated packages, which contain a backported patch to correct this issue.

Solution

Update the affected ghostscript packages.
