I was just attacked by somebody issuing a LIST /*/../*/../*/../*/.../*
command which caused ftpd to use up all CPU on the server and thrash
the disk. I have a limit on anonymous ftps so they could only get
several of these going.

Has anybody heard about this, or better yet know of a patch to fix it?

Cheers.
