    <p>
    The vendor reported a directory traversal vulnerability when processing
    DCC SEND requests.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote, authenticated user could send a specially crafted DCC SEND
    request to overwrite arbitrary files with the privileges of the user
    running ZNC, and possibly cause the execution of arbitrary code e.g. by
    uploading a malicious ZNC module.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All ZNC users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=net-irc/znc-0.074&quot;</code>
  </resolution>
