nethack: Privilege escalation/remote code execution/crash in configuration parsing (CVE-2019-19905)
NetHack 3.6.x before 3.6.4 is prone to a buffer overflow vulnerability when reading very long lines from configuration files. This affects systems that have NetHack installed suid/sgid, and shared systems that allow users to upload their own configuration files.
