Scroller Redhat
Essential php53 patch addresses a memory leak vulnerability for CentOS, enhancing safe XML processing. Update immediately.
Updated php53 packages that fix one security issue are now available for Red Hat Enterprise Linux 5.6 Extended Update Support

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/site/articles/11258

Summary

PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Server.
A buffer overflow flaw was found in the way PHP parsed deeply nested XML documents. If a PHP application used the xml_parse_into_struct() function to parse untrusted XML content, an attacker able to supply specially-crafted XML could use this flaw to crash the application or, possibly, execute arbitrary code with the privileges of the user running the PHP interpreter. (CVE-2013-4113)
All php53 users should upgrade to these updated packages, which contain a backported patch to resolve this issue. After installing the updated packages, the httpd daemon must be restarted for the update to take effect.
