An information disclosure vulnerability was discovered in Drupal before 7.27. When pages are cached for anonymous users, form state may leak between anonymous users. Sensitive or private information recorded for one anonymous user could thus be disclosed to other users interacting with the same form at the same time (CVE-2014-2983).
Multiple security issues in Drupal before 7.29, including a denial of service issue, an access bypass issue in the File module, and multiple cross-site scripting issues (CVE-2014-5019, CVE-2014-5020, CVE-2014-5021, CVE-2014-5022).
Drupal has been updated to version 7.29, fixing this and other bugs.
