Almost every program nowadays is compiled with W^X (--no_execstack) by default which means the memory is not executable and writable at once (Windows equivalent is DEP). Still a good example of how a basic overflow can lead to arbitrary code execution. A follow-up post using ROP or return-to-libc would be interesting, with W^X enabled.
