We evaluated the source to the exploit, and made some changes to

hate to tell you this, but these things have already been fixed, and by
several in parallel.  latest vr series ftpd, with redhat's changes merged
in:

ftp://ftp.vr.net/pub/wu-ftpd/wu-ftpd-2.4.2-vr17.tar.gz


Interestingly enough, from the code that we saw, there was already
code in the source to handle buffer overflows, but it wasn't
implemented for all of the functions.

not to mention path-filter
