"The nethack and slashem packages are vulnerable to a buffer overflow
exploited via a long '-s' command line option. This vulnerability
could be used by an attacker to gain gid 'games' on a system where
nethack is installed.

Additionally, some setgid binaries in the nethack package have
incorrect permissions, which could allow a user who gains gid 'games'
to replace these binaries, potentially causing other users to execute
malicious code when they run nethack.

Note that slashem does not contain the file permission problem
CAN-2003-0359."
