This is a PoC exploit for CVE-2021-3156, a heap-based overflow vulnerability in sudo. The exploit is a C program that creates a shared library (libnss_X/P0P_SH3LLZ_.so.2) that overflows the heap when sudoedit is called. The exploit can be built using the provided Makefile and run using the sudo-hax-me-a-sandwich executable. The exploit can be used to gain root privileges on a vulnerable system. The exploit is not specified to be used in a particular context, but it can be used in a manual mode where the user can specify the lengths of the smash, null stomp, and lc_all. The exploit also includes a brute force target finding feature that uses GNU parallel to try different combinations of lengths to find a successful exploit.
