We leave the stack for the glibc heap, where the allocator's own bookkeeping is the attack surface. You will learn chunks…
A format string bug — printf(user_input) instead of printf("%s", user_input) — gives you both an arbitrary memor…
Every chain so far hardcoded addresses, which only works with ASLR off. This is the keystone that makes it work on a real target: …
