Angband Bugreports

If you find a bug then report it to me at rr9@thangorodrim.net. I can't fix the bug if I don't know of it. You should include the following informations in your bugreports: A description of the bug or problem (it wouldn't be a bug-report without this). The Angband version number, what system you are using and what compiler you used (if you compiled it yourself). A way to reproduce the bug if you can find one. A savefile is often very helpful to track the problem down. It's very difficult to fix a bug that I can't reproduce. A fix for the problem if you know one. :-)

Known bugs in Angband 2.9.1

Avavir has a wrong activation

Description: Avavir has the ACTIVATE flag but no "A:" activation line.

Fix (14th September 2000): avavir_activation.diff

The "Bubbles" vault has inaccessible areas

Description: There is a bug in one of Chris Weisiger's new vaults: number 30, "Bubbles". The two "bubbles" in the bottom right corner are inaccessible, and surrounded entirely by permanent rock. This should obviously not be the case. This can be checked by (a) changing the colour of permanent rock so it is not the same colour as normal granite, and (b) then wizard-lighting the level with (CTRL-A)+W.

Fix (14th September 2000): bubbles_vault.diff

init1.c contains dead code

Description: Looking at init1.c and the parsing of the p_info.txt file, it appears that the code for checking the "I:" lines is duplicated.

The recall artifact activation does work in ironman mode

Fix (14th September 2000): recall_ironman.diff

Loading the bitmap file in the X11 version fails on some systems

Description: Loading the *.bmp files fails with the message "Incorrect BMP file format" on various types of Unix machines. This problem is caused by some code in maid-x11.c that depends heavily on a specific byte order, size of variables, and internal layout of structs.

Fix (17th September 2000): bitmap_loading.diff

Security hole (buffer overflow) in Angband and variants

Description: The code for the parsing of command-line parameters contains a bug that allows a buffer overflow attack. This enables malicious users on multi-user systems where Angband runs setuid or setgid to get access as the owner of the executable (usually this is user "games"). Update: The "ANGBAND_PATH" environment-variable also allows a buffer-overflow attack.

Fix (7th October 2000): security_problem.diff

The Windows version restricts window sizes to 80x24 tiles

Fix (7th October 2000): big_windows.diff

The pref-file parsing allows the specification of invalid indices for some entries

Description: The code for the parsing of a pref-file line doesn't check for negative indices for objects, monsters, features, and other things. This allows the user to directly write to the memory of the program and can be abused by malicious users to get get access as the owner of the executable (usually this is user "games") on multi-user systems where Angband runs setuid or setgid.

Fix (7th October 2000): pref_security.diff

The weight carried by the player can reach strange values when carrying huge amounts of heavy objects

Fix (2nd November 2000): total_weight.diff

Fix (21st January 2001): max_level.diff

The low hitpoint warning is added to the message history, but not displayed on the screen

Fix (22nd January 2001): hitpoint_warn.diff

The curses version (main-gcu.c) doesn't clean up the terminal properly on exit

Fix (23rd January 2001): quit_curses.diff

Security hole in the file display

Description: The file-reader used in the help-file display and the knowledge menu can be used to read files that should only be readable by group games (when running setgid games).

Fix (27th January 2001): show_file.diff

Compiling with the Cygwin compiler fails

Fix (1st February 2001): cygwin.diff
