Download WordPress 3.9.2

Version 3.9.2 of WordPress has been released. With this program, which is made available under a gpl license, it is possible to set up and maintain a weblog. WordPress is easy to set up and can be up and running in under five minutes if a server with PHP and MySQL is already available. There are possibilities to further extend the functionality of WordPress, in addition to blogging, and improve the appearance with plugins and themes to adjust. Version 3.9 includes a newer version of TinyMCE, the component used for text entry. This update mainly contains security updates.

WordPress 3.9.2 Security Release

This release fixes a possible denial of service issue in PHP’s XML processing, reported by Nir Goldshlager of the Salesforce.com Product Security Team. It was fixed by Michael Adams and Andrew Nacin of the WordPress security team and David Rothstein of the Drupal security team. This is the first time our two projects have coordinated joint security releases.

WordPress 3.9.2 also contains other security changes:

• Fixes a possible but unlikely code execution when processing widgets (WordPress is not affected by default), discovered by Alex Concha of the WordPress security team.
• Prevents information disclosure via XML entity attacks in the external GetID3 library, reported by Ivan Novikovy or ONsec.
• Adds protections against brute attacks against CSRF tokens, reported by David Tomaschik of the Google Security Team.
• Contains some additional security hardening, like preventing cross-site scripting that could be triggered only by administrators.

We appreciated responsible disclosure of these issues directly to our security team. For more information, see the release notes or consult the list of changes.
