(RHSA-2014:0311) Critical: php security update

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 floating point
numbers from their text representation. If a PHP application converted
untrusted input strings to numbers, an attacker able to provide such input
could cause the application to crash or, possibly, execute arbitrary code
with the privileges of the application. (CVE-2009-0689)

It was found that PHP did not properly handle file names with a NULL
character. A remote attacker could possibly use this flaw to make a PHP
script access unexpected files and bypass intended file system access
restrictions. (CVE-2006-7243)

All php users are advised to upgrade to these updated packages, which
contain backported patches to correct these issues. After installing the
updated packages, the httpd daemon must be restarted for the update to
take effect.
