Mozilla protocol abuse

The Mozilla application platform currently has an unpatched input validation flaw which allows you to specify arbitrary command line arguments to any registered URL protocol handler process. Jesper Johansson already detailed parts of this on his blog on July 20, http://msinfluentials.com/blogs/jesper/. I wrote a vulnerability report on July 18 together with a proof-of-concept exploit that targeted Thunderbird 2.0.0.4.
Thunderbird 2.0.0.5 was released on July 19 and incidentally fixed this specific attack vector through its "osint" command line flag. It is now 6 days later and people should have had time to update their Thunderbird installations, so I have decided to publish my vulnerability report together with the exploits as they detail how to handle XPI exploitation.
The HTML version can be found at http://larholm.com/2007/07/25/mozilla-protocol-abuse/ A ZIP file with the report and the XPI exploits can be found athttp://larholm.com/media/2007/7/mozillaprotocolabuse.zip
