  <description>
    <p>Multiple vulnerabilities have been discovered in Ettercap:</p>
    
    <ul>
      <li>Ettercap does not handle temporary files securely (CVE-2010-3843).</li>
      <li>A format string flaw in Ettercap could cause a buffer overflow
        (CVE-2010-3844).
      </li>
      <li>A stack-based buffer overflow exists in Ettercap (CVE-2013-0722).</li>
    </ul>
  </description>
  <impact type="normal">
    <p>A remote attacker could entice a user to load a specially crafted
      configuration file using Ettercap, possibly resulting in execution of
      arbitrary code with the privileges of the process or a Denial of Service
      condition. 
    </p>
    
    <p>A local attacker could perform symlink attacks to overwrite arbitrary
      files with the privileges of the user running the application.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All Ettercap users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=net-analyzer/ettercap-0.7.5.2"
    </code>
