1. Overview:

PHP is a general purpose scripting language widely used in World Wide Web (WWW) pages and applications.

A heap overflow vulnerability has been found in the PHP 'xmlrpc' extension. An attacker could potentially exploit a PHP script which uses XML-RPC to execute code as the user the web server runs as. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2007-1864 to this issue.

A vulnerability has been reported in the PHP 'ftp' extension. In certain configurations, an attacker could exploit a PHP script using FTP to send arbitrary commands to the FTP server. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2007-2509 to this issue.

More information about these vulnerabilities can be found in the security advisory issued by RedHat Linux:
