NetHack 3.6.7: Release Notes

The NetHack DevTeam is announcing the release of NetHack 3.6.7 on February 16, 2023

NetHack 3.6.7 is the official release of NetHack that follows NetHack 3.6.6.

This release primarily corrects a security issue present in NetHack versions 3.6.2, 3.6.3, 3.6.4, 3.6.5, and 3.6.6. For details about the security issues please see https://www.nethack.org/security. You are encouraged to update to NetHack 3.6.7 as soon as possible.

Here's a brief synopsis of the handful of bug fixes included in NetHack 3.6.7:

invalid status highlight color could be maliciously used to corrupt memory
formatting corpse names used internal buffers differently from formatting other objects and could potentially clobber memory
during engraving, spaces were counted instead of non-space (cherry-pick of 4e0a1e04 from NetHack-3.7)
avoid potential buffer overflow in append_str()
resolve missing dependency in NetHack.sln
code in include/tradstdc.h was trying to suppress warn_unused result by defining warn_unused_result to an empty string and that began causing a build error within a system-supplied header file cdefs.h when using Ubuntu Impish 21.10; disable that for any Linux and macOS gcc unless GCC_URWARN is defined to force it back into effect
update_inventory() after leash goes slack
player assigned name for monsters, specific objects, or object types could be longer than what was intented to be allowed; for 'curses', much longer
Windows: added winflexbison to travis-ci configuration to permit full build of levcomp and dgncomp
Windows: a bad chdir specified in win/win32/dgnstuff.mak caused full build to abort
Windows: the console.rc file had outdated information stating 3.6.3 when the official 3.6.6 binary had been built.
Windows: switch from using keyhandling dll's to incorporating the three variations (default, ray, 340) in sys/winnt/nttty.c
curses: cherry-picked selectsaved code from 3.7 for menu of save files
NetHackW: fix delayed rendering of cursor when using farlook

All of the fixes have been published on the public Git repository for the game. A more complete list can be found in the game's sources in doc/fixes36.7. As usual, a warning that some entries in that file may also be "spoilers".

Existing saved games and bones files from 3.6.0 through to 3.6.6 should work with 3.6.7, assuming that the same build configuration options were used with the same compiler.

Checksums (sha256) of binaries that you have downloaded from nethack.org can be verified on Windows platforms using: certUtil -hashfile nethack-367-win-x86.zip SHA256

The following command can be used on most platforms to help confirm the location of various files that NetHack may use: nethack --showpaths

As with all releases of the game, we appreciate your feedback. Please submit any bugs using the problem report form. Also, please check the "known bugs" list before you log a problem - somebody else may have already found it.

Happy NetHacking!
