46 is a program used to regulate game playing.
48 expects to be invoked with the name of a game that a user wishes to play.
49 This is done by creating symbolic links to

74 will be displayed to any user requesting a game.

89 Two problems result from
91 running the games setuid
93 First, all games that allow users to run
95 commands should carefully
96 set both the real and effective user id's immediately before executing
97 those commands. Probably more important is that
102 so that compromising a game will result only in
103 the user's ability to play games at will. Secondly, games which previously
104 had no reason to run setuid and which accessed user files may have to
