Red Hat Security Advisory 2012-1256-01
Posted Sep 11, 2012
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2012-1256-01 - Ghostscript is a set of software that provides a PostScript interpreter, a set of C procedures and an interpreter for Portable Document Format files. An integer overflow flaw, leading to a heap-based buffer overflow, was found in Ghostscript's International Color Consortium Format library. 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.

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.

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.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/knowledge/articles/11258

5. Bugs fixed (http://bugzilla.redhat.com/):
