   * Advisory ID: DRUPAL-SA-CONTRIB-2014-097
   * Project: Nodeaccess [1]     (third-party module)
   * Version: 6.x, 7.x
   * Date: 2014-October-08
   * Security risk: 13/25 ( Moderately Critical)
     AC:Basic/A:User/CI:Some/II:Some/E:Proof/TD:Uncommon [2]
   * Vulnerability: Access bypass

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

Nodeaccess is a Drupal access control module which provides view, edit and
delete access to nodes.

This module enables you to inadvertently allow an author of a node
view/edit/delete the node in question (who may not have access). The module
over-eagerly grants read/write/delete access to all authors of nodes.

In addition, a node that is unpublished, but is granted node specific
permissions will obey the node specific permissions and not the unpublished
content permission for the role.


-------- CVE IDENTIFIER(S) ISSUED
--------------------------------------------

   * /A CVE identifier [3] will be requested, and added upon issuance, in
     accordance
            with Drupal Security Team processes./

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

   * Nodeaccess 6.x-1.x versions prior to 6.x-1.5.
   * Nodeaccess 7.x-1.x versions prior to 7.x-1.4.

Drupal core is not affected. If you do not use the contributed Nodeaccess [4]
module,
       there is nothing you need to do.

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

Ensure that you are using the latest version of the Nodeaccess module when
installing. For existing nodes, please ensure that the author permissions are
correct.

   * If you use the Nodeaccess module for Drupal 6.x, upgrade to Nodeaccess
     6.x-1.5 [5]
   * If you use the Nodeaccess module for Drupal 7.x, upgrade to Nodeaccess
     7.x-1.4 [6]
