Solution

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