    buffer that fails to take into account the size of the reply header.
    </p>
  </description>
  <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.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All NBD Tools users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=sys-block/nbd-2.8.2-r1&quot;</code>
