_IF_ the stack smashing protection works it will reduce this bug into a pure
local DoS yes. I have seen no proof so far that the SSP stack smashing
protection is 100% effective against all types of overflows.

The Adamantix kernels are compiled with SSP (aka propolice), which is the same
thing used to compile the OpenBSD kernel. It protects against some, but not
all, overflows.
