wu-ftpd MAIL_ADMIN overflow Vulnerability Scan

Vulnerability Scan Summary
Checks the banner of the remote wu-ftpd server

Detailed Explanation for this Vulnerability Test

The remote Wu-FTPd server seems to be vulnerable to a remote flaw.

This version 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, a possible hacker 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.

Solution : Upgrade to Wu-FTPd 2.6.3 when available
Threat Level: High
