Subject: [Security-news] SA-CONTRIB-2012-134 - Views -
	Privilege Escalation

View online:

  * Advisory ID: DRUPAL-SA-CONTRIB-2012-134
  * Project:
    (third-party module)
  * Version: 6.x
  * Date: 2012-August-29
  * Security risk: Critical [1]
  * Exploitable from: Remote
  * Vulnerability: Privilege escalation

-------- DESCRIPTION  

The Views module provides a flexible method for Drupal site designers to
control how lists and tables of content, users, taxonomy terms and other data
are presented.

The module incorrectly modifies the global user object in some situations
when a view has a uid argument and performs validation on that argument.

This vulnerability is mitigated by the fact that it only affects sites with
more roles than default where a role with a low role ID has more privileges
than other roles on the site and where untrusted (i.e. potentially malicious)
users are granted several of those roles.

CVE: Requested


  * Views 6.x-2.x versions prior to 6.x-2.16.

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

-------- SOLUTION  

Install the latest version:

  * If you use the Views module for Drupal 6.x, upgrade to Views 6.x-2.16 [2]

Also see the
project page.

-------- REPORTED BY  

  * Derek Wright [3] of the Drupal Security Team
  * John Preto [4]

-------- FIXED BY  

  * Derek Wright [5] one of module maintainers, also of the Drupal Security


  * Greg Knaddison [6] of the Drupal Security Team
