  </description>
  <impact type="normal">
    <p>A remote attacker, by performing a man-in-the-middle attack, could
      execute arbitrary code, conduct a Denial of Service, or have other
      unspecified impacts.
    </p>
  </impact>
  <workaround>
    <p>Users are advised to not trust insecure protocols such as HTTP and to
      turn off any mirror updates utilizing such channels.
    </p>
  </workaround>
  <resolution>
    <p>All Rootkit Hunter users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=app-forensics/rkhunter-1.4.6"
    </code>
