  * Advisory ID: DRUPAL-SA-CORE-2009-009
  * Project: Drupal core
  * Version: 5.x, 6.x
  * Date: 2009-December-16
  * Security risk: Not critical

  * Vulnerability: Cross site scripting

-------- DESCRIPTION  
---------------------------------------------------------

Multiple vulnerabilities were discovered in Drupal.
.... Contact category name cross-site scripting

The Contact module does not correctly handle certain user input when
displaying category information. Users privileged to create contact
categories can insert arbitrary HTML and script code into the contact module
administration page. Such a cross-site scripting attack may lead to the
malicious user gaining administrative access. Wikipedia has more information
about cross-site scripting [1] (XSS). This issue affects Drupal 6.x and
Drupal 5.x.
.... Menu description cross-site scripting

The Menu module does not correctly handle certain user input when displaying
the menu administration overview. Users privileged to create new menus can
insert arbitrary HTML and script code into the menu module administration
page. Such a cross-site scripting attack may lead to the malicious user
gaining administrative access. Wikipedia has more information about
cross-site scripting [2] (XSS). This issue affects Drupal 6.x only.
-------- VERSIONS AFFECTED  
---------------------------------------------------

  * Drupal 5.x before version 5.21.
  * Drupal 6.x before version 6.15.

-------- SOLUTION  
------------------------------------------------------------

Install the latest version:
  * If you are running Drupal 6.x then upgrade to Drupal 6.15 [3].
  * If you are running Drupal 5.x then upgrade to Drupal 5.21 [4].

If you are unable to upgrade immediately, you can apply a patch to secure
your installation until you are able to do a proper upgrade. Theses patches
fix the security vulnerability, but do not contain other fixes which were
released in Drupal 5.21 or Drupal 6.15.
