hi,

don't know if this is the right place to ask, but here it goes:

i was notified by one of my users (!) about the recent samba vulnerability
(CAN-2004-0930 [1]) that this is indeed easily "exploitable" by just
issuing commands with long wildcard-patterns in the filename part, just as:

<smb-share>:\> dir ******.exe

ok, my smbd went crazy and the "dir" command was waiting for the result.
but: when i mounted the smb-share under linux (mount -t smbfs ....) and
issuing

$ ls /mnt/smb-share/*******.exe

"ls" returned *instantly* with "No such file or directory" and smbd did
not go crazy. now i ask myself: how comes?

thank you for comments,
Christian.
