43 is a program used to regulate game playing.

46 This is done by creating symbolic links to

91 Two problems result from

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