   * Advisory ID: DRUPAL-SA-CONTRIB-2015-175
   * Project: Block Class [1]     (third-party module)
   * Version: 7.x
   * Date: 2015-December-16
   * Security risk: 19/25 ( Critical)
     AC:None/A:Admin/CI:All/II:All/E:Theoretical/TD:All [2]
   * Vulnerability: Cross Site Scripting

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

This module enables you to add custom classes to blocks.
The module doesn't sufficiently scrub class names written by a malicious
block class administrator.
This vulnerability is mitigated by the fact that an attacker must have a role
with the permission "Administer block classes".

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

Install the latest version:

   * If you use the block_class module for Drupal 7.x, upgrade to block_class
