WebReturn Oriented Programming (or ROP) is the idea of chaining together small snippets of assembly with stack control to cause the program to do more complex things. As we saw in buffer overflows, having stack control can be very powerful since it allows us to overwrite saved instruction pointers, giving us control over what the program does next.
