Security Professionals, On Wednesday, April 7, 2004, Emmanouel Kellinis reported to Bugtraq that the following HTML tag would cause IE to crash: <iframe src="?"> Please see post: http://www.securityfocus.com/archive/1/359767/2004-04-05/2004-04-11/0 I discovered this bug in January 2004 and reported it to Microsoft on January 28, 2004. After working with Microsoft, I decided to wait until the bug was fixed before announcing it. In my opinion, this is part of responsible disclosure. I hope Microsoft will publicly reply to this post and confirm that I was the individual who originally reported the bug to them.
