Seems like there never were security issues. At least, none that were talked about widely. I think that should be expected for a single player game. Almost all games are hack-able in some way of course but hacking a single player game is mostly an exercise in replay-ability. On a related note: Doom apparently does contribute to security proof of concepts though. http://www.techtimes.com/articles/15606/20140916/security-expert-hacks-canon-pixma-printer-to-play-doom-highlights-security-weakness.htm http://www.techtimes.com/articles/15606/20140916/security-ex... Which makes me wonder if the non-clearing memory issue exists for the printer's video driver and whether that could be used to retrieve something like a saved password or ssh key.
