Revisited Internet Explorer 6 DoS Bug

["Peter Kruse" <kruse () krusesecurity dk>]

Hi all,

The problem is surely related to the serial communication ports. It can
also, besides from the AUX call, be reproduced with a file:///c:/com1 or
file:///c:/com2 and so on ;-)

It´s possible to remotely DoS a browser this way. I´ve recieved several
reports, that this issue affects many other browsers, and can cause
Mcirosoft Windows to completely crash.  

I have put up a new testpage using a simple: <img src=file:///c:/com1>
at:

[Don´t go there unless you really want to!]

This attack can also be conducted with HTML based e-mails.

Med venlig hilsen // Kind regards
