"The remote host is affected by the vulnerability described in GLSA-200603-23
(NetHack, Slash'EM, Falcon's Eye: Local privilege escalation)
NetHack, Slash'EM and Falcon's Eye have been found to be incompatible
with the system used for managing games on Gentoo Linux. As a result,
they cannot be played securely on systems with multiple users.
Impact :
A local user who is a member of group 'games' may be able to modify the
state data used by NetHack, Slash'EM or Falcon's Eye to trigger the
execution of arbitrary code with the privileges of other players.
Additionally, the games may create save game files in a manner not
suitable for use on Gentoo Linux, potentially allowing a local user to
create or overwrite files with the permissions of other players.
Workaround :
Do not add untrusted users to the 'games' group."
