[security-news at drupal.org]

  * Advisory ID: DRUPAL-SA-CONTRIB-2010-032
  * Project: Taxonomy Breadcrumb (third-party module)
  * Versions: 6.x-1.x, 5.x-1.x
  * Date: 2010-March-31
  * Security risk: Critical
  * Exploitable from: Remote
  * Vulnerability: Cross Site Scripting

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

The Taxonomy Breadcrumb module generates taxonomy based breadcrumbs on node
pages and taxonomy/term pages. This module does not properly sanitize
taxonomy term name and, for 6.x, node titles when displayed in breadcrumbs,
leading to a Cross Site Scripting (XSS [1]) vulnerability. XSS
vulnerabilities may lead to compromise of administrative accounts or other
attacks against site visitors.

  * Taxonomy Breadcrumb module for Drupal 6.x version prior to 6.x-1.1.
  * Taxonomy Breadcrumb module for Drupal 5.x versions prior to 5.x-1.5.

Drupal core is not affected. If you do not use the contributed Taxonomy
Breadcrumb module, there is nothing you need to do.
