We can not take credit OR blame for those enhancements - including
nethack - that MandrakeSoft adds to Red Hat Linux.
/etc/redhat-release remains for compatibility, as does the RedHat link
on the CD-ROM images. Linux Mandrake 6.1 was released before Red Hat
Linux 6.1 anyway, so they can't brand the next version as "Red Hat
Linux 6.1 with enhancements."
You said, "I tried it on (the irony) /usr/games/nethack, which is SGID
root by default on RH6.0." This is a false statement. We do not
loose face, you do by making utterly false claims. We do not ship any
GNOME programs with setuid/gid bits that give anything more than
'games' group access and 'wtmp' group access (which is
gnome-pty-helper, not a full GNOME application, therefore immune to
your reported bug).
So, my point: You can not use your exploit on GNOME applications as
shipped in Red Hat Linux 6.0 to gain extra privileges beyond the
current user privileges that allow you to do anything beyond changing
your high score in gnomine.
