I think I found a Security vulnerability in IE 6.0



Not a very major issue, but a malicous user has the ability to crash Internet
Explorer 6.0 on an unsuspecting user's computer., not sure to the extent of
what browser versions this affects, as I have only tested IE 6.0. The issue
occurs when the offending page contains an IFRAME and the following
Javascript code is run in:

document.all['myIFrame'].src = "javascript:;";
window.top.close();

In my situation the code was run from a modal dialog so there was no
security warning about the close. My assumption is that the Iframe is in a
vulnerable state when the close() function is called, causing a memory
leak/protection fault of some kind.. just my guess..
Regards,
Andrew
