Check your version number for WU-FTPD.  It should be 2.6.0 or higher.

A quick jump over to CERT shows you need to have version 2.6.0 of 
wu-ftpd or latter to avoid the known attacks against it.  Looking at
both the frozen and unstable releases we should be up to date.  It may
be that there is a new exploit.
