* Advisory ID: DRUPAL-SA-CONTRIB-2012-039 * Project: Language icons [1] (third-party module) * Version: 6.x, 7.x * Date: 2012-March-14 * Security risk: Moderately critical [2] * Exploitable from: Remote * Vulnerability: Cross Site Scripting

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

The Language icons module adds icons to language links generated by the Locale and Content Translation modules in core. The module does not sanitize some of the user-supplied data before displaying it, leading to a Cross Site Scripting (XSS [3]) vulnerability. This vulnerability is mitigated by the fact that an attacker must have a role with the permission "administer languages".

-------- VERSIONS AFFECTED ---------------------------------------------------

* Language icons 6.x-2.x versions prior to 6.x-2.1. * Language icons 7.x-1.x versions prior to 7.x-1.0.

Drupal core is not affected. If you do not use the contributed Language icons [4] module, there is nothing you need to do.

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

Install the latest version:

* If you use the Language icons module for Drupal 6.x, upgrade to Language icons 6.x-2.1 [5] * If you use the Language icons module for Drupal 7.x, upgrade to Language icons 7.x-1.0 [6]
