The remote host is running SmartFTP - a FTP client.

There is a flaw in the remote version of this software which may 
allow an attacker to execute arbitrary code on this host.

To exploit it, an attacker would need to set up a rogue FTP
server and have a user on this host connect to it.

Solution : Upgrade to version 1.0.976.x or newer
Risk factor : High";
