Oracle's critical security update for Java 7 addresses vulnerabilities that may allow unauthorized system access on Windows. Users should upgrade without delay
Updated ghostscript packages that fix one security issue are now available for Red Hat Enterprise Linux 5 and 6

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

Summary

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.
