If you use SourceForge services, you may have noticed problems using SVN/CVS. SourceForge posted this message to their Status Page:

( 2006-07-13 09:23:52 - Project CVS Service, Project Shell Service, Project Subversion (SVN) Service, SourceForge.net Web Site ) A recent kernel exploit was released that allowed a non admin user to escalate privileges on the host pr-shell1. We urge all users who frequent this host to change their password immediately and check their project group space for any tampering. As a precaution, we have blocked access to all project resources by password until the user resets their password. After the password has been reset, project resources should be accessible within 5 minutes.

Basically, to regain CVS/SVN/etc. access, you must change your password. This can be done here:

http://sourceforge.net/account/change_pw.php

After this, you will be prompted for your password once more when committing, then it'll work normally.
