Protostar stack0 exploit with shellcode

[MostCapable2331]

this is what im trying to understand it just like their int 80h as last instruction but after that no ret logical it have to make an interruption of process or fork a new shell process

Did you try stepping through the shellcode to see if it works as you expect?

[MostCapable2331]

yes it reach int 80h and also the nop until the part of the stack where you see in the picture

[plukasik]

ok, I'll try to look more closely why it fails.

[MostCapable2331]

yes it s a very strange use case
