- # This PoC exploits a bof in parsing a very long config file ( > 250 bytes )
- # As in the advisory there's other bofs. but i just researched this one to
- # make a Proof-Of-Concept Code.
- # In Gentoo Linux (distro where this poc was developed) there isn't any suid
- # atari800 binaries. i suppose.. :D
- # -
- # Tested against Atari800 from portage.
