ProFTPD NLST Command Argument Handling Remote Overflow

This script is Copyright (C) 1999-2016 Tenable Network Security, Inc.

Synopsis :

The remote FTP server is affected by a buffer overflow vulnerability.

Description :

It was possible to crash the remote FTP server by issuing a specially
crafted command, such as 'NLST aaaXXXX%u%[...]%u%u%u%%u%653300u%n'
where 'XXXX' is replaced with four characters - ASCII values 0xDC,
0x4F, 0x07 and 0x08. This issue is known to affect ProFTPD version
1.2.0pre6, although other FTP servers may be affected as well.

It is likely that a remote attacker can leverage this issue to execute
arbitrary code on the remote host, subject to the privileges under
which the service runs.
