unsafebf

An unsafe brainfuck interpreter. It uses stack as memory directly.

Features

• Simple code
• Dynamically allocated large memory
• A little fast
• Allows RCE for attacker
• Non portable (It depends on POSIX read and write functions that do not use stack.)

How to

gcc main.c -o unsafebf
./unsafebf "Some bf code"

FAQ

Q. It's not working in my environment

This software depends on the implementation heavily. I confirmed it works in x86_64 and -O3 flags.
