Breakpoint 2, 0x0000000000400e2d in phase_1 () Now let's take a quick look at the disassebly to see what variables are being used. Enter disas and you will get a chunk of assembly for the function phase_1 which we put our breakpoint at. (gdb) disas. Dump of assembler code for function phase_1: => 0x0000000000400e2d <+0>: sub $0x8,%rsp.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 ctarget dump and search for touch2, it looks something like this: \n
