The remote FTP server is affected by a buffer overflow vulnerability.
The remote WU-FTPD server seems to be vulnerable to an off-by-one
overflow when dealing with huge directory structures.
An attacker may exploit this flaw to obtain a shell on this host.
Note that Nessus has solely relied on the banner of the remote server
to issue this warning so it may be a false-positive, especially if the
patch has already been applied.
