Description

Welcome to this crackme. Only executing shellcode on the stack, which executes /bin/sh is a valid solution. Do not make the stack executeable with a tool. Do not patch. I hope that you will learn how to bypass nx. Aslr has to be disabled with "echo 0 /proc/sys/kernel/randomize_va_space". If you are stuck, a little hint will be in the comments. Good luck!
