Aleph One’s excellent Smashing the Stack for Fun and Profit article from 1996 has long been the go-to for anyone looking to learn how buffer overflow attacks work. But the world has changed a lot since then, and the original attacks will not generally work on modern 64-bit machines.

What cannot easily be avoided any more though is 64-bit execution environments.
