For this phase, we will be using the program rtarget instead of ctarget \n. This phase is the same as phase 2 except you are using different exploit method to call touch2 and pass your cookie. \n.

Instead, your exploit string will redirect the program to execute an existing procedure. Function getbuf is called within CTARGET by a function test having the following C code: 1 void test() 2 {3 int val; 4 val = getbuf(); 5 printf("No exploit. Getbuf returned 0x%x", val); 6}{"payload":{"allShortcutsEnabled":false,"fileTree":{"":{"items":[{"name":"Attack Lab Notes","path":"Attack Lab Notes","contentType":"file"},{"name":"Attack Lab Phase ...Attack Lab实验代码见GitHub 简介Attack Lab的内容针对的是CS-APP中第三章中关于程序安全性描述中的栈溢出攻击。在这个Lab中,我们需要针对不同的目的编写攻击字符串来填充一个有漏洞的程序的栈来达到执行攻击代码的目的,攻击方式分为代码注入攻击与返回导向编程攻击。本实验也是对旧版本中IA32 ...
