Description SATOH Fumiyasu 2004-02-20 02:06:58 UTC
In source/libsmb/nmblib.c, name_mangle() uses toupper(3) against a NetBIOS
name string. If a string has multibyte characters encoded in CP932 (dos cahrset
name for Windows Japanese Edition) and has some specific CP932 words
(e.g. "\x8A\x6A", means "Core" in Japanese/CP932), words in the string is changed
into another word (e.g. "\x8A\x4A", means "Open" in Japanese/CP932).

Do not use toupper(3) for strings which can have multibyte characters.

784 is fixed so I guess this one is as well.  Closing.

sorry for the same, cleaning up the database to prevent unecessary reopens of bugs.
