The reason is that when you run the "dir" command Samba does the
processing and chokes. When you try the latter command "ls" Linux\Unix
processes the command and has no problems.

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.
