  <impact type="high">
    <p>
    A remote attacker could send a malicious request that can result
    in the execution of arbitrary code with the rights of the NBD server.

  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>

    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=sys-block/nbd-2.8.2-r1"</code>
