The vulnerability exists due to the way Firefox handles messages to the parent process that trigger the 'Click to Play' permission prompt to be shown. A remote attacker can create a specially crafted web page and assign arbitrary permissions instead of 'Click to Play' permission, if the user accepted the permission request.
