I think that it would be very cool if RSBAC would be able to fix one big
problem: buffer overflows:

So far I am aware of 3 types of overflows:
The ones execing in the stack or heap
The ones that return to PLT
The ones that return in libc

So far I was able to fix 1 and 3 of that list by taking use of Libsafe
(which is LD_PRELOADED before every binary) and PaX to set the stack and the
heap to non-exec. Setting Data and BSS to non-exec would be the next step in
PaX development.
