- --------------------------BEGIN INCLUDED TEXT--------------------

	A confirmed flaw exists in two XML-RPC libraries for PHP allowing 
	an attacker to remotely execute arbitrary code.  These XML-RPC 
	libraries are used by many popular PHP applications.

	A web server running an affected PHP application may be remotely

	The following libraries are confirmed to be vulnerable:
	- pear-XML_RPC 1.4.0 and prior
	- PHPXMLRPC  1.1.1 and prior
	The following applications using these libraries are confirmed to be
	vulnerable at the time of writing:
	- phpMyFAQ 1.4.11 and prior
	- Drupal 4.6.3 and prior
	- eGroupWare and prior
	- phpAdsNew 2.0.5 and prior
	- PostNuke .760 and prior
	Any PHP applications using the affected libraries mentioned may be 
	similarly vulnerable.

	As with other vulnerabilities in web applications, exploitation may be
	trivial and could result in compromise of a web server.  Potential 
	impacts to a compromised web server could include defacement, data 
	theft, or the installation of malware such as backdoors or botnet


	Patch any PHP applications accordingly or disable functionality relying
	on the above libraries.

	Listed below are vendor statements for the libraries and applications 
	confirmed vulnerable at the time of writing, detailing temporary
	mitigations and version upgrades:
	- phpMyFAQ

	- drupal

	- eGroupWare
	- phpAdsNew

	- PostNuke
