   * Advisory ID: DRUPAL-SA-CONTRIB-2014-84
   * Project: Avatar Uploader [1]     (third-party module)
   * Version: 6.x, 7.x
   * Date: 2014-08-20
   * Security risk: 16/25 ( Critical)
     AC:Basic/A:User/CI:All/II:None/E:Exploit/TD:100 [2]
   * Vulnerability: Information Disclosure

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

The Avatar Uploader enables you to upload user pictures in a user-friendly
way, like Quora and Facebook.

The module doesn't sufficiently check the picture path when a user crops the
picture in the uploader panel allowing a malicious user to make specially
crafted requests to obtain sensitive server files that are readable by the
webserver user.

This vulnerability is mitigated by the fact that an attacker must know or
guess the relative path out of the temporary directory and to the sensitive
files.
