[Pkg-samba-maint] Bug#416185: samba-common: net rpc share causes segfault when invoked with -l parameter on windows hosts

[Tommaso Colombo]

Package: samba-common
Version: 3.0.24-6
Followup-For: Bug #416185

When trying to list the shares on remote windows hosts, the following
error occurs:

$ net share -U Guest% -l -S mary-space

Enumerating shared resources (exports) on remote server:


Share name   Type     Description
----------   ----     -----------
Segmentation fault


The same command without the -l options succeeds, and so do the
smbclient -L command and the net command using the rap protocol instead
of the rpc protocol:

$ net share -U Guest% -S mary-space
IPC$
D$
iTunes Music
ADMIN$
C$


$ smbclient -U Guest% -L mary-space
Domain=[MARY-SPACE] OS=[Windows 5.1] Server=[Windows 2000 LAN Manager]

        Sharename       Type      Comment
        ---------       ----      -------
        IPC$            IPC       IPC remoto
        D$              Disk      Condivisione predefinita
        iTunes Music    Disk
        ADMIN$          Disk      Amministrazione remota
        C$              Disk      Condivisione predefinita
Domain=[MARY-SPACE] OS=[Windows 5.1] Server=[Windows 2000 LAN Manager]

        Server               Comment
        ---------            -------

        Workgroup            Master
        ---------            -------


$ net rap share -U Guest% -l -S mary-space

Enumerating shared resources (exports) on remote server:


Share name   Type     Description
----------   ----     -----------
IPC$         IPC      IPC remoto
D$           Disk     Condivisione predefinita
iTunes Music Disk
ADMIN$       Disk     Amministrazione remota
C$           Disk     Condivisione predefinita


The problem occurs only when quering windows host. The same command
works just fine when used on linux hosts

$ net share -U Guest% -l -S mirtexxan

Enumerating shared resources (exports) on remote server:


Share name   Type     Description
----------   ----     -----------
film         Disk
IPC$         IPC      IPC Service (mirtexxan server)
ADMIN$       IPC      IPC Service (mirtexxan server)



The problem seems to be amd64-specific, but I only own a x86 box and an
an amd64 box, so I can't be sure.
I will do a fresh install of Debian to test wether this error depends on
specific configurations.

Regards,

Tommaso
