This repository contains a Python script (gen_shellcode.py), based on pwntools, to generate a shellcode implementing CVE-2022-0847.The shellcode is based on this Poc: antx. I analyzed the code of the PoC and its execution with strace to catch all the system calls required to make the exploit, and at first I wrote a C program that uses syscall.h; it was ...Pwntools is a CTF framework and exploit development library.
