It does seem that most people want the security benefits of ASLR. Applications that never touch any un-trusted input aren't that common. And IIUC there's not enough bits in a 32 bit pointer for ASLR to be effective.

But is ALSR actually effective ? It seems every month someone reports a hardware bug that makes it ineffective.

I'd be interested in the answer. Like many security features, it is breakable, but does it slow attackers down enough to be useful?
