There is no flaw in nethack that we're aware of, this is an interaction between nethack and the policy used for managing games on gentoo that results in a security problem. > Are any other distributions/platforms vulnerable to a problem in nethack like > this?

Unlikely, gentoo uses a non-standard method of installing games, that is very unlikely to be used elsewhere. > If this problem is on their end, are other games/applications able to trigger > it? > > They've essentially wiped these fundamental applications (sorry) off their > tree for the time being, that's pretty severe. Yes, Gentoo does not use the standard setgid system for games that store system-wide high scores, save games, etc, and as a result anyone can manipulate the high score tables or save games. Nethack was simply not designed to work this way and does not expect users to be able to modify it's state data arbitrarily, and as a result makes assumptions about the format of the files that may not hold true on Gentoo. We have decided to temporarily revoke these packages while these issues are resolved.
