* Advisory ID: DRUPAL-SA-CORE-2011-003
  * Project: Drupal core [1]
  * Version: 7.x
  * Date: 2011-July-27
  * Security risk: Less critical [2]
  * Exploitable from: Remote
  * Vulnerability: Access bypass

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

.... Access bypass in private file fields on comments.

Drupal 7 contains two new features: the ability to attach File upload fields
to any entity type in the system and the ability to point individual File
upload fields to the private file directory.

If a Drupal site is using these features on comments, and the parent node is
denied access (either by a node access module or by being unpublished), the
file attached to the comment can still be downloaded by non-privileged users
if they know or guess its direct URL.

This issue affects Drupal 7.x only.

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

  * Drupal 7.x before version 7.5.

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

Install the latest version:

  * If you are running Drupal 7.x then upgrade to Drupal 7.5 or 7.6.

The Security Team has released both a pure security update without other bug
fixes and a security update combined with other bug fixes and improvements.
You can choose to either only include the security update for an immediate
fix (which might require less quality assurance and testing) or more fixes
and improvements alongside the security fixes by choosing between Drupal 7.5
and Drupal 7.6. Read the announcement [3] for more information.
