[security-news AT drupal.org]

View online: http://drupal.org/node/1782580

  * Advisory ID: DRUPAL-SA-CONTRIB-2012-139
  * Project: PDFThumb [1] (third-party module)
  * Version: 7.x
  * Date: 2012-September-12
  * Security risk: Moderately critical [2]
  * Exploitable from: Remote
  * Vulnerability: OS Injection

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

PDFThumb module creates thumbnail images of PDF files.
The module doesn't sufficiently escape user-entered values when executing
commands on the server allowing an attacker to execute whatever commands are
available to the web server user (e.g. www-data).
This vulnerability is mitigated by the fact that an attacker must have a role
with the permission "Administer PDFThumb".

CVE: Requested

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

  * PDFThumb 7.x-1.x versions prior to 7.x-1.1

Drupal core is not affected. If you do not use the contributed PDFThumb [3]
module, there is nothing you need to do.

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