SA-CONTRIB-2009-027 - Printer, e-mail and PDF versions - Cross-site 
Security advisories for contributed projects  Drupal 5.x  Drupal 6.x
Drupal Security Team - May 13, 2009 - 16:40

    * Advisory ID: DRUPAL-SA-CONTRIB-2009-027
    * Project: Printer, e-mail and PDF versions (third-party module)
    * Versions: 5.x, 6.x
    * Date: 2009-May-13
    * Security risk: Moderately critical
    * Exploitable from: Remote
    * Vulnerability: Multiple vulnerabilities


When outputting user-supplied data Drupal strips potentially dangerous HTML 
attributes and tags or escapes characters which have a special meaning in 
HTML. This output filtering secures the site against cross site scripting 
attacks via user input.

Certain byte sequences that are valid in the UTF-8 specification are 
potentially dangerous when interpreted as UTF-7. Internet Explorer 6 and 7 
may decode these characters as UTF-7 if they appear before the 
<meta http-equiv="Content-Type" /> tag that specifies the page content as 
UTF-8, despite the fact that Drupal also sends a real HTTP header 
specifying the content as UTF-8. This behaviour enables malicious users to 
insert and execute Javascript in the context of the website if site visitors 
are allowed to post content. Note, this vulnerability is identical to that 
fixed for Drupal core by DRUPAL-SA-CORE-2009-005

Such a cross site scripting (XSS) attack may lead to a malicious user 
gaining full administrative access.

Versions Affected

    * Versions of "Printer, e-mail and PDF versions" for Drupal 5.x prior 
      to 5.x-4.7
    * Versions of "Printer, e-mail and PDF versions" for Drupal 6.x prior 
      to 6.x-1.7

Drupal core is not affected. If you do not use the contributed "Printer,
e-mail and PDF versions" module, there is nothing you need to do.


Install the latest version:

    * If you use "Printer, e-mail and PDF versions" for Drupal 5.x 
        upgrade to Printer, e-mail and PDF versions 5.x-4.7
    * If you use "Printer, e-mail and PDF versions" for Drupal 6.x 
        upgrade to Printer, e-mail and PDF versions 6.x-1.7
