Hmmm. If there was any kind of rational model behind Linux security — for example a model with a small kernel which could be automatically proved correct — then this would make sense.

But Linux security is all over the place. There are surely many combinations of system calls that allow you to bypass checks and escalate privileges ("backdoors") and this is just one of them. No one has written the clever program to find the others yet, but it's just a matter of time.

Rich.
