WordPress 2.5.1 Security Update

WordPress has released a security update for version 2.5.1 of the blogging software. Users that allow open registrations (for user comments or for multi-author blogs) should update immediately. The update also includes over 70 other fixes for the media uploader, widget administration and layout. WordPress users can download these corrected copies of wp-includes/pluggable.php, wp-admin/includes/media.php, and wp-admin/media.php. Simply replace your existing copies of these files with the new copies and avoid the inevitable exploitation when the hole is publicly announced.
