Original Bulletin: 

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

    * Advisory ID: DRUPAL-SA-CONTRIB-2010-051
    * Project: Heartbeat (third-party module)
    * Version: 6.x
    * Date: 2010-May-19
    * Security risk: Critical
    * Exploitable from: Remote
    * Vulnerability: Cross Site Scripting


The Heartbeat project contains a suite of modules to display user activity 
on a website. These modules do not properly sanitize some of their output, 
allowing certain users the ability to insert arbitrary HTML and script code. 
Such a cross site scripting (XSS) attack may lead to a malicious user 
gaining full administrative access. Depending on how the modules are 
configured, this vulnerability may extend to relatively unprivileged 
users, such as those with the ability to post comments, user "shouts" 
or other content.

Versions affected

    * Heartbeat for Drupal 6.x versions prior to 6.x-4.9

Drupal core is not affected. If you do not use the contributed Heartbeat 
modules, there is nothing you need to do.


Install the latest version:

    * If you use the Heartbeat module for Drupal 6.x, update to 
	Heartbeat 6.x-4.9. 

See also the Heartbeat project page.
