The new version fixes:
- A vulnerability found in the OpenID module that allows a malicious user to log in as other users on the site, including administrators, and hijack their accounts
- Other less critical issues
In response to the new version we have released Bitnami Drupal 7 and 6 installers, virtual machines and Amazon EC2, Google, Azure, and VMware cloud images that fix these issues. There are no new features or non-security-related bug fixes in these releases.
