Note: Versions mentioned in the description apply only to the upstream nethack package and not the nethack package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

In NetHack before 3.6.5, detecting an unknown configuration file option can cause a buffer overflow resulting in a crash or remote code execution/privilege escalation. This vulnerability affects systems that have NetHack installed suid/sgid and shared systems that allow users to upload their own configuration files. Users should upgrade to NetHack 3.6.5.
