* Advisory ID: DRUPAL-SA-CONTRIB-2012-132
* Project: Announcements [1] (third-party module)
* Version: 6.x
* Date: 2012-August-29
* Security risk: Moderately critical [2]
* Exploitable from: Remote
* Vulnerability: Access bypass

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

The Announcements module creates an "announcement" content type and provides
both node views and block lists.

The module doesn't sufficiently check node access under certain conditions.

This vulnerability is mitigated by the fact that an attacker must have a role
with the permission "access announcements".

CVE: Requested

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

* Announcements 6.x-1.x versions prior to 6.x-1.5.

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

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

Install the latest version:

* If you use the Announcements module for Drupal 6.x, upgrade to
Announcements 6.x-1.5 [4]

Also see the Announcements [5] project page.

-------- REPORTED BY

-------- FIXED BY
------------------------------------------------------------

-------- COORDINATED BY
