The OpenID module in Drupal 6.x before 6.30 and 7.x before 7.26 allows remote OpenID users to authenticate as other users via unspecified vectors.

Cross-site scripting (XSS) vulnerability in Drupal 6.x before 6.28 and 7.x before 7.19, when running with older versions of jQuery that are vulnerable to CVE-2011-4969, allows remote attackers to inject arbitrary web script or HTML via vectors involving unspecified Javascript functions that are used to select DOM elements.

Cross-site scripting (XSS) vulnerability in the Image module in Drupal 7.x before 7.24 allows remote authenticated users with certain permissions to inject arbitrary web script or HTML via the description field.

Cross-site scripting (XSS) vulnerability in the Color module in Drupal 7.x before 7.24 allows remote attackers to inject arbitrary web script or HTML via vectors related to CSS.

Drupal 6.x before 6.29 and 7.x before 7.24 uses the PHP mt_rand function to generate random numbers, which uses predictable seeds and allows remote attackers to predict security strings and bypass intended restrictions via a brute force attack.

The form API in Drupal 6.x before 6.29 and 7.x before 7.24, when used with unspecified third-party modules, performs form validation even when CSRF validation has failed, which might allow remote attackers to trigger application-specific impacts such as arbitrary code execution via application-specific vectors.

Open redirect vulnerability in the Overlay module in Drupal 7.x before 7.24 allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via unspecified vectors.

The printer friendly version functionality in the Book module in Drupal 6.x before 6.28 and 7.x before 7.19 does not properly restrict access to node that are part of a book outline, which allows remote authenticated users with the "access printer-friendly version" permission to read node titles and possibly node content via unspecified vectors.

The Image module in Drupal 7.x before 7.19, when a private file system is used, does not properly restrict access to derivative images, which allows remote attackers to read derivative images of otherwise restricted images via unspecified vectors.

The Image module in Drupal 7.x before 7.20 allows remote attackers to cause a denial of service (CPU and disk space consumption) via a large number of new derivative requests.
