"Th remote Wu-FTPD server fails to properly check bounds on a pathname
when Wu-Ftpd is compiled with MAIL_ADMIN enabled resulting in a buffer
overflow.  With a specially crafted request, an attacker can possibly
execute arbitrary code as the user Wu-Ftpd runs as (usually root)
resulting in a loss of integrity, and/or availability. 

It should be noted that this vulnerability is not present within the
default installation of Wu-Ftpd. 

The server must be configured using the 'MAIL_ADMIN' option to notify
an administrator when a file has been uploaded. 

*** Nessus solely relied on the banner of the remote server
*** to issue this warning, so it may be a false positive." );

arbitrary commands on the server. In addition, a MAIL_ADMIN which has
been found to be insecure has been disabled. We do not recommend
deploying WU-FTPD in situations where security is required."
