Multiple vulnerabilities have been discovered in Drupal, a fully-featured content management framework. The Common Vulnerabilities and Exposures project identifies the following issues:
Christian Mainka and Vladislav Mladenov reported a vulnerability in the OpenID module that allows a malicious user to log in as other users on the site, including administrators, and hijack their accounts.
Matt Vance and Damien Tournoud reported an access bypass vulnerability in the taxonomy module. Under certain circumstances, unpublished content can appear on listing pages provided by the taxonomy module and will be visible to users who should not have permission to see it.
These fixes require extra updates to the database which can be done from the administration pages. Furthermore this update introduces a new security hardening element for the form API. Please refer to the upstream advisory at drupal.org/SA-CORE-2014-001 for further information.
For the stable distribution (wheezy), these problems have been fixed in version 7.14-2+deb7u2.
For the testing distribution (jessie), these problems have been fixed in version 7.26-1.
For the unstable distribution (sid), these problems have been fixed in version 7.26-1.
We recommend that you upgrade your drupal7 packages.
