  <title>Samba: Remote printing non-vulnerability</title>
  <synopsis>
    Samba has a bug with out of sequence print change notification requests,
    but it cannot be used to perform a remote denial of service attack.

  <background>
    <p>
    Samba is a freely available SMB/CIFS implementation which allows
    seamless interoperability of file and print services to other SMB/CIFS
    clients.
    </p>
  </background>
  <description>
    <p>
    Due to a bug in the printer_notify_info() function, authorized users
    could potentially crash their smbd process by sending improperly
    handled print change notification requests in an invalid order. Windows
    XP SP2 clients can trigger this behavior by sending a
    FindNextPrintChangeNotify() request before previously sending a
    FindFirstPrintChangeNotify() request.
    </p>
  </description>
  <impact type="low">
    <p>
    We incorrectly thought that this bug could be exploited to deny service
    to all Samba users. It is not the case, this bug has no security impact
    whatsoever. Many thanks to Jerry Carter from the Samba team for
    correcting our mistake.
    </p>
  </impact>
  <workaround>
    <p>
    There is no need for a workaround.
    </p>
  </workaround>
  <resolution>
    <p>
    Samba users can keep their current versions.
    </p>
  </resolution>
