You don't really need to know much of assembly to find the canary. ![]() Canary is a value placed on stack and checked by the compiler to see if anything corrupts canary value. Now the hardest part: we need to find in assembly where canary value was stored and loaded on stack. The interesting part here is the caller of _stack_chk_fail. #3 0x00007fcbdefbd0a2 in _GI_fortify_fail "stack smashing detected") at fortify_fail.c:26 ![]() Program terminated with signal SIGABRT, Aborted.
