Vulnerabilities

NetHack is a single player dungeon exploration game.

In NetHack before 3.6.6, some out-of-bound values for the hilite_status option can be exploited.

NetHack before version 3.6.0 allowed malicious use of escaping of characters in the configuration file (usually .nethackrc) which could be exploited.

In NetHack before 3.6.5, an invalid extended command in value for the AUTOCOMPLETE configuration file option can cause a buffer overflow resulting in a crash or remote code execution/privilege escalation.

In NetHack before 3.6.5, an extremely long value for the MENUCOLOR configuration file option can cause a buffer overflow resulting in a crash or remote code execution/privilege escalation.

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.

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.

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.

In NetHack before 3.6.5, an invalid argument to the -w command line option can cause a buffer overflow resulting in a crash or remote code execution/privilege escalation.

NetHack 3.6.x before 3.6.4 is prone to a buffer overflow vulnerability when reading very long lines from configuration files.

Buffer overflow in (1) nethack 3.4.0 and earlier, and (2) falconseye 1.9.3 and earlier, which is based on nethack, allows local users to gain privileges via a long -s command line option.
