Original message :

Hola:
Well, as it seems that is the Microsoft Crash mounth, let see another

one:

---------------------------------
<html>
<form>
<input type crash>
</form>
</html>
---------------------------------
This will crash IE with the following error:
"Unhandled exception in iexplore.exe (SHLWAPI.DLL):

0xC0000005: Access

Violation" It's a null pointer overwrite, so it's not easly 
exploitable...

This HTML also crash Outlook, Frontpage, and all the

Microsoft programs
that >use the shlwapi.dll library to render web code.

Plain HTML is a dangerous language :)


Added : 

It also seems to crash explorer.exe when the .html file 
containing the code is copied into any folder !! It may work 
since windows is trying to create a view in Windows explorer. 
Indeed, it doesn't work when the file is copied in the desktop.

Tested on Windows XP with Office XP.


        Not only on winXP; it has the same effect on win2000 server and
advanced server; windows.NET advanced server & interprise server RC1;
RC2 & the release version. With office XP or 2000 or without them.
Of course you could delete the file through the command prompt. :D
        Another interesting thing; in win2000 and winXP, the browser (
iexplore or explorer or ... ) hangs & shows the message that send this
error to microsoft & restart the browser.
In win.NET it crashes the browser & restarts it without any message.
But.....
        After u log off & again log on; it now shows the messages to
you; one by one.
It shows the stability of .NET system that keeps the messages for u. :))
