In NetHack before 3.6.5, too long of a value for the SYMBOL 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.
