(RHSA-2012:1256) Moderate: ghostscript security update

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.
