CentOS Errata and Security Advisory CESA-2009:0420

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 missing boundary check was found in Ghostscript’s CCITTFax decoding
filter. 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-2007-6725)

Users of ghostscript are advised to upgrade to these updated packages,
which contain backported patches to correct these issues.
