The first three deal with Code injection attacks and the last two phases deal with return operated attacks. Solutions are described below: Phase 1: Phase one is a simple solution approach.consist of the eight hexadecimal digits (ordered from most to least significant) without a leading “0x.”. • Recall that a string is represented in C as a sequence of bytes followed by a byte with value 0. Type. “man ascii” on any Linux machine to see the byte representations of the characters you need.最开始试图用 Phase 4 的办法，一个个尝试可行的 mov 方案，后来发现可能性太多了，一个个搜起来太麻烦（如本题从 %rax 到 %rsi 就中间周转了 2 次，最差可能要试 8 ^ 2 = 64 种情况）；因为 pop 、mov 本身的字节指令有规律，完全可以在 rtarget 中将所有的 pop 、mov ...One of the possible solutions to this issue is to push the %rsp value again after returning from the touch function and add more padding. The most import is to review the stack after you perform the operation and make sure it's the same as after your attack is done. 2. Assignees.

If you jumped/returned to the 87 byte inside the LEA (instead of the LEA opcode itself), then yes 3 NOPs and then a c3 ret would have the same effect as 2 NOPs and then a c3 ret.
