  Fastream NETFile FTP/Web Server HTTP HEAD DoS (Exploit)
------------------------------------------------------------------------


SUMMARY

" <http://www.fastream.com/netfileserver.htm> Fastream NETFile FTP/Web 
Server is a secure FTP server and Web-based file server combined together 
in one program. Our claim is that it is the "easiest to setup and 
administer server" on the Internet!"

Due to improper handling of keepalive in HTTP HEAD requests, it is 
possible to cause a denial of service to Fastream NETFile FTP/Web Server.
