Attack target: when ctarget ctarget runs, the position on the stack is continuous, so the data on the stack is executable. Phase 1. task: when ctarget returns from getbuf, execute the code of touch1 instead of returning to test. Suggestions:With this form of attack, you can get the program to do almost anything. The code you place on the stack is called the exploit code. This style of attack is tricky, though, because you must get machine code onto the stack and set the return pointer to the start of this code.
