(RHSA-2009:0345) 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.

Multiple integer overflow flaws which could lead to heap-based buffer
overflows, as well as multiple insufficient input validation flaws, were
found 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 which could cause
Ghostscript to crash, or, potentially, execute arbitrary code when opened
by the victim. (CVE-2009-0583, CVE-2009-0584)

All users of ghostscript are advised to upgrade to these updated packages,
which contain a backported patch to correct these issues.
