Wordpress should probably be upgraded to address security vulnerabilities in version 2.8.6. This includes at least one SQL injection for authors (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=605603), some XSS vulnerabilities, and I think some others. The full list of vulnerabilities can probably be obtained through wordpress's release notes at http://codex.wordpress.org/Version_2.9 http://codex.wordpress.org/Version_2.9.1 http://codex.wordpress.org/Version_2.9.2 http://codex.wordpress.org/Version_3.0 http://codex.wordpress.org/Version_3.0.1 http://codex.wordpress.org/Version_3.0.2 http://codex.wordpress.org/Version_3.0.3 Unfortunately, upstream isn't too great about publishing detailed reports of their security issues. This might also be a good time to talk to the wordpress-mu maintainer about getting rid of the wordpress-mu package and working together on 3.x, now that wordpress and wordpress-mu have been merged.
