probably, and ideally so, but you have to remember that you are already dealing with software not behaving because it has allowed a buffer overflow. it depends on the hardware and software, some systems are more robust than others. i honestly haven't played with *nix for along time, and never at that low level so i can't say for sure for *nix. also, depending on where the buffer is it might just overflow into memory space used by apache or whatever in which case it may not be able to do major damage, but it might well be able to diddle with things that are normally secure. it's sort of like drawing a high voltage arc to the keyboard on an electronic door lock, it will usually open the door, but it depends to some extent on the implementation.
