fpg, Re: There is no buffer-overflow exploit in shruggle
That's the point. Try to follow along.
Viruses can be made without buffer-overflow, and Shruggle is proof. Do you think that all the world's virus writers are going to give up when their buffer-overflow code doesn't work, or that they'll keep in writing buffer-overflow code, even after the hardware repels their attempts? No.
The point is that hackers will change their tactics to create viruses that don't overflow buffers, now that the hardware prevents it. Your fallacy is that you fail to look at viruses as coming from intelligent and malicious people. NX isn't going to stop them from writing different kinds of viruses.
Next year, AMD based systems will still be susceptible to all the viruses that come out with alternatives to buffer-overflow. You seem to think this will be a small number, because it's a small number today, but the *point* is that it won't be a smaller number, because all the people smart enough to write a buffer-overflow virus today will be writing different viruses next year, and AMD's hack of a solution isn't going to stop them.
