As you may already know the Mozilla's "patch" for the shell protocol security issue is merely a global configuration change. But is it enough?
If an attacker has a file writing access to the user's default profile directory, or somehow manages to update/create the file user.js (or even worse - mozilla.cfg) he can override the patch's configuration change, and enable the shell protocol handler again. Trying to apply the patch again won't override the attacker's configuration change, and doing it manually through the about:config interface will be enough only until the user closes the browser. Tested on Mozilla Firefox 0.9.1. What do you think? _______________________________________________ Full-Disclosure - We believe in it. Charter: http://lists.netsys.com/full-disclosure-charter.html
