Of course, don't publicize it. But consider a though experiment: From a security perspective, does it really increase risk? There are many ways to kill someone that are much simpler than figuring out what pacemaker they have, finding a 0day, designing an attack and implementing it. This vulnerability doesn't necessarily increase the risk that someone will be murdered. EDIT: Or if you want to attack the pacemaker, use radiation from microwaves or similar devices. At least according to signs posted in many places, they are dangerous to users of pacemakers.
