phpmyadmin, subject to XSS vulnerability, again, redux. If you're not running version 2.8.2.1, update quickly.

If you use PHPMyAdmin, I would suggest you put it behind .htaccess/.htpasswd authentication, or protect it from being accessed from other locations around the net -- while you're still not protected, you are at least making it much more difficult for the systematic scans to discover your whereabouts.
Addendum to the sitedepth note: You may delete files in the previous_versions directory after the upgrade has been performed.
