In NetHack before 3.6.5, unknown options starting with -de and -i 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 influence command line
options. Users should upgrade to NetHack 3.6.5.
