  <description>
    <p>Multiple vulnerabilities have been discovered in tcpdump:</p>
    
    <ul>
      <li>The olsr_print function function contains an integer underflow error
        (CVE-2014-8767)
      </li>
      <li>The geonet_print function function contains multiple integer
        underflow errors (CVE-2014-8768)
      </li>
      <li>The decoder for the Ad hoc On-Demand Distance Vector protocol
        contains an out-of-bounds memory access error (CVE-2014-8769)
      </li>
      <li>The ppp_hdlc function contains a buffer overflow error
        (CVE-2014-9140)
      </li>
    </ul>
  </description>
  <impact type="normal">
    <p>A remote attacker may be able to send a specially crafted packet,
      possibly resulting in execution of arbitrary code or a Denial of Service
      condition.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All tcpdump users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=net-analyzer/tcpdump-4.6.2-r1"
    </code>
