    Package        : libpam-smb
    Vulnerability  : buffer overflow
    Problem-Type   : remote
    Debian-specific: no
    CVE Ids        : CAN-2003-0686
    libpam-smb is a PAM authentication module which makes it possible to
    authenticate users against a password database managed by Samba or a
    Microsoft Windows server.  If a long password is supplied, this can
    cause a buffer overflow which could be exploited to execute arbitrary
    code with the privileges of the process which invokes PAM services.
    For the stable distribution (woody) this problem has been fixed in
    version 1.1.6-1.1woody1.
    For the unstable distribution (sid) does not contain a libpam-smb
    We recommend that you update your libpam-smb package.
