Here's what I wrote about the Windows AUX bug in 1996: http://groups.google.com/groups?selm=01bbf024%2463d4cd00%24a78103c7%40ti ac.net.tiac.net&oe=UTF-8&output=gplain
3). Including the HTML tag <img src="file:///aux"> in an HTML attachment will crash the Windows 95 version of Navigator. Attempting to shudown Navigator can also takedown Windows 95. And here's another variation of the bug also from 1996: http://groups.google.com/groups?selm=01bbd759%24722c7d00%24a78103c7%40ti ac.net.tiac.net&oe=UTF-8&output=gplain An interesting thing is that Microsoft has their own version of the "Exploder" control. Its called ActiveMovie. Its designed to play AVI movies within Internet Explorer. It becomes an exploder control if it is told to play a movie from the URL file:///AUX . This URL locks up ActiveMovie and often crashes Windows 95.

I have succesfully DoS�ed several machines using a simple <img src=c:\aux> in a HTML page. In order to test this remotely I have put up a POC page that can be accessed here: http://www.krusesecurity.dk/aux_dos.htm. If your browser crash you�re vulnerable to a remote DoS using the ooold aux trick. HTML based e-mails will also crash already vulnerable systems. If a system is vulnerable this DoS can be succesfully conducted in many ways.

Smith Sendt: 8. juli 2003 01:40 Til: 'Dan Williams'; [EMAIL PROTECTED] Emne: RE: [Full-Disclosure] Internet Explorer 6 DoS Bug Does an HTML IMG tag like <img src=c:\aux> also cause a crash? This kind of tag can be embedded in an HTML email message. If the bug shows up also in an IMG tag, then an Email reader like Outlook or Outlook Express can be DoSed. Ditto for Hotmail and Yahoo mail.
