View online: http://drupal.org/node/1762470

* Advisory ID: DRUPAL-SA-CONTRIB-2012-131
* Project: Email Field [1] (third-party module)
* Version: 6.x, 7.x
* Date: 2012-August-29
* Security risk: Less critical [2]
* Exploitable from: Remote
* Vulnerability: Access bypass

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

The email module provides a field type (CCK / FieldAPI) for storing email
addresses. Furthermore, it provides a formatter to output the email address
as a link to a contact form. The contact form formatter allows a site visitor
to email the stored address without letting them see what that e-mail address
is.

The module didn't sufficiently check access for the contact form page,
allowing a site visitor to email the stored address on the entity without
having access to the entity itself.

CVE: Requested

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

* Email Field 6.x-1.x versions prior to 6.x-1.2.
* Email Field 7.x-1.x versions prior to 7.x-1.1.

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

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

Install the latest version:

* If you use the Email Field module for Drupal 6.x, upgrade to Email Field
6.x-1.3 [4]
* If you use the Email Field module for Drupal 7.x, upgrade to Email Field
7.x-1.2 [5]

Also see the Email Field [6] project page.
