Attack lab phase 1

Phase 2 involves injecting a small code and calling function touch2 while making it look like you passed the cookie as an argument to touch2 \n. If you look inside the rtarget dump and search for touch2, it looks something like this: \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} 4-4
