"Updated php53 packages that fix one security issue are now available
for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having
critical security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from
the CVE link in the References section.

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."
