  * Advisory ID: DRUPAL-SA-CONTRIB-2010-104
  * Project: Relevant Content (third-party module)
  * Version: 5.x, 6.x
  * Date: 2010-November-17
  * Security risk: Less critical
  * Exploitable from: Remote
  * Vulnerability: Information Disclosure

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

The Relevant Content module provides a block and CCK field which contain
links to other nodes on the site which are considered "relevant" to the
current nodes based on number of shared taxonomy terms. The Relevant Content
module does not implement node access logic properly, resulting in the
disclosure of node titles and relationships between nodes that the user
cannot normally access.

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

  * Relevant Content module for Drupal 5.x versions prior to 5.x-1.4
  * Relevant Content module for Drupal 6.x versions prior to 6.x-1.5

Drupal core is not affected. If you do not use the contributed Relevant
Content [1] module, there is nothing you need to do.

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

Install the latest version:
  * If you use the Relevant Content module for Drupal 5.x upgrade to Relevant
    Content 5.x-1.4 [2]
  * If you use the Relevant Content module for Drupal 6.x upgrade to Relevant
    Content 6.x-1.5 [3]

See also the Relevant Content project page [4].
