The Joomla! project has just released a new version that fixes multiple vulnerabilities including one that is considered a high priority. You can find more information about these issues on the Joomla! blog post.
Due to these security issues, we have released Bitnami Joomla! 3.4.6 installers, virtual machines and Amazon EC2, Google, Windows Azure, Oracle, Digital Ocean and VMware Air cloud images that fix these issues. If you already have a running version of Bitnami Joomla!, you can update it from the administration panel.
Have questions about Bitnami Joomla! or the security issue? Post to our community forum, and we would be happy to help you.
