O

C is a buffer o in FreeFloat FTP Server 1.0 triggered through the NOOP command.

Improper bounds checking on user supplied input allows an attacker to send an o payload which can corrupt process memory within the FTP service.

Because the service is network accessible and does not require authentication, exploitation may be performed remotely.
