A WordPress plugin brought to you by Search Engine Journal.
WordPress 3.9.2 has just been rolled out as a security release for all previous versions. WordPress strongly recommends that you update your sites immediately.
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.
Other security changes in WordPress 3.9.2 include:
- Fixes a possible but unlikely code execution when processing widgets (WordPress is not affected by default).
- Prevents information disclosure via XML entity attacks in the external GetID3 library.
- Adds protections against brute attacks against CSRF tokens.
- Contains some additional security hardening, like preventing cross-site scripting that could be triggered only by administrators.
Sites that support automatic background updates will be updated to WordPress 3.9.2 within 12 hours. To get this latest security update manually, point your browser to Dashboard → Updates and simply click “Update Now”.
