I know this will soon be patched, but would it be theoretically possible to run a root exploit that would root a phone and install a superuser management app? Root your phone with just a text. That would be an interesting exploit.
AND... could one possibly use this exploit to push their own patch? Could someone who has a payload with a fix mass-message all android users? That payload could also try and send itself to others within the then-patched device's contact list.
