Drupal 6.x before 6.23 and 7.x before 7.11 does not verify that Attribute Exchange (AX) information is signed, which allows remote attackers to modify potentially sensitive AX information without detection via a man-in-the-middle (MITM) attack.
Cross-site request forgery (CSRF) vulnerability in the Aggregator module in Drupal 6.x before 6.23 and 7.x before 7.11 allows remote attackers to hijack the authentication of unspecified victims for requests that update feeds and possibly cause a denial of service (loss of updates due to rate limit) via unspecified vectors.
The File module in Drupal 7.x before 7.11, when using unspecified field access modules, allows remote authenticated users to read arbitrary private files that are associated with restricted fields 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.
Drupal 6.x before 6.27 and 7.x before 7.18 displays information for blocked users, which might allow remote attackers to obtain sensitive information by reading the search results.
The file upload feature in Drupal 6.x before 6.27 and 7.x before 7.18 allows remote authenticated users to bypass the protection mechanism and execute arbitrary PHP code via a null byte in a file name.
The image module in Drupal 7.x before 7.14 does not properly check permissions when caching derivative image styles of private images, which allows remote attackers to read private image styles.
Drupal 7.x before 7.14 does not properly restrict access to nodes in a list when using a "contributed node access module," which allows remote authenticated users with the "Access the content overview page" permission to read all published nodes by accessing the admin/content page.
