Today on Bugtraq a message was posted that listed a possible vulnerability in Firefox 1.5.0.3.  Several attempts by various Handlers were unable to determine that a new vulnerability actually exists.  The link posted to Bugtraq took us to a web page that was purported to run the exploit, which did not appear to work.  Stay tuned for further details.

The "exploit" appears to be a simple link to an audio file (claims to be an image). If you, as instructed by the exploit page, open the "image", you will launch your media player and load a local .wav file. Nothing actually "bad" about that as far as we can tell, so this is probably just a joke to point out some of the social engineering aspects of hyperlinked media.
