Oracle Linux 5 / 6 : ghostscript (ELSA-2012-1256)

This script is Copyright (C) 2013-2014 Tenable Network Security, Inc.


Synopsis :

The remote Oracle Linux host is missing one or more security updates.

Description :

From Red Hat Security Advisory 2012:1256 :

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 Schönefeld for reporting this issue.

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