Comment: This bulletin contains three (3) Drupal Security Advisories
Revision History: September 29 2009: Added CVE References
September 24 2009: Initial Release
- --------------------------BEGIN INCLUDED TEXT--------------------
* Advisory ID: DRUPAL-SA-CONTRIB-2009-060
* Project: Meta tags / Nodewords (third-party module)
* Version: 6.x
* Date: 2009-September-23
* Security risk: Less critical
* Exploitable from: Remote
* Vulnerability: Access bypass
- -------- DESCRIPTION -------------------------------------------------------
The Meta tags (also known as Nodewords) module provides meta tags based on
node titles. In certain conditions, the node meta tags were not respecting
access permissions, potentially exposing content not available otherwise.
- -------- VERSIONS AFFECTED -------------------------------------------------
* Meta tags for Drupal 6.x before Meta tags 6.x-1.1
Drupal core is not affected. If you do not use the contributed Meta tags
module, there is nothing you need to do.
- -------- SOLUTION ----------------------------------------------------------
Install the latest version:
* If you use Drupal 6.x upgrade to Meta tags 6.x-1.1 [1].
Also see the Meta tags [2] project page.

* Advisory ID: DRUPAL-SA-CONTRIB-2009-061
* Project: Markdown Preview (third-party module)
* Version: 6.x
* Date: 2009 September 23
* Security risk: Less critical
* Exploitable from: Remote
* Vulnerability: Cross Site Scripting
- -------- DESCRIPTION -------------------------------------------------------
The Markdown Preview module provides a live preview pane that displays the
rendered HTML output of your Markdown input. When displaying the live
preview, the module does not properly escape user entered data, leading to a
cross-site scripting (XSS [1]) vulnerability. Such an attack may lead to a
malicious user gaining full administrative access.
- -------- VERSIONS AFFECTED -------------------------------------------------
* Markdown Preview for Drupal 6.x
Drupal core is not affected. If you do not use the contributed Markdown
Preview module, there is nothing you need to do.
- -------- SOLUTION ----------------------------------------------------------
The Markdown Preview module has been abandoned and its releases have been
unpublished. It is recommended that it be disabled and removed from your
server if in use. For Markdown live preview functionality for nodes and
comments, use the Live module [2], which properly escapes the user entered
data using the content's current input format. See the Markdown Preview
project page [3] for instructions how to enable Markdown preview
functionality with the Live module [4].

Reported by David Needham [5].

On behalf of Drupal security team, this module has been handled by Stéphane
Corlosquet [6], Oleg Terenchuk [7], and Dave Reid [8].

* Advisory ID: DRUPAL-SA-CONTRIB-2009-062
* Project: Devel (third-party module)
* Version: 5.x, 6.x
* Date: 2009-September-23
* Security risk: Less critical
* Exploitable from: Remote
* Vulnerability: Cross Site Scripting
- -------- DESCRIPTION -------------------------------------------------------
The Devel module contains many useful developer functions, such as a query
log and the display of variables. When using the variable editor, the module
does not properly sanitize the output of the variable name before display,
leading to a cross-site scripting (XSS [1]) vulnerability. Such an attack may
lead to a malicious user gaining full administrative access.
- -------- VERSIONS AFFECTED -------------------------------------------------
* Devel versions 6.x prior to 6.x-1.18
* Devel versions 5.x prior to 5.x-1.2
Drupal core is not affected. If you do not use the contributed Devel module,
there is nothing you need to do.
- -------- SOLUTION ----------------------------------------------------------
Install the latest version:
* If you use the Devel for Drupal 6.x upgrade to Devel 6.x-1.18 [2]
* If you use the Devel for Drupal 5.x upgrade to Devel 5.x-1.2 [3]
