"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)

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