[security-news AT drupal.org]

  * DRUPAL-SA-CONTRIB-2010-107
  * Services (third-party module)
  * Version: 6.x
  * Date: 2010-Dec-01
  * Security risk: Critical
  * Exploitable from: Remote
  * Vulnerability: Access Bypass

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

The Services module allows users to expose Drupal functionality to remote
users. Services provides the ability for users to update nodes contained in a
drupal install via the services api. When using using the node.save service
it is possible for a user to supply a specifically crafted node or format
type and circumvent access control checks.

This only affects sites that are using the node.save service.

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

  * Services module for Drupal 6.x versions prior to 6.x-2.3.
  * Drupal core is not affected. If you do not use the contributed Services
    module, there is nothing you need to do.

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

Install the latest version:

  * If you use the Services module for Drupal 6.x upgrade to Services 6.x-2.3
