    <package name="net-analyzer/echoping" auto="yes" arch="*">
      <unaffected range="ge">6.0.2_p434</unaffected>

  <background>
    <p>Echoping is a small program to test performances of a
      remote host by sending it TCP packets.
    </p>
  </background>
  <description>
    <p>A boundary error exists within the “TLS_readline()” function, which
      can be exploited to overflow a global buffer by sending an overly long
      encrypted HTTP reply to Echoping. Also, a similar boundary error exists
      within the “SSL_readline()” function, which can be exploited in the
      same manner.
    </p>
  </description>
  <impact type="normal">
    <p>A remote attacker could send a specially crafted HTTP reply, possibly
      resulting in a Denial of Service condition.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All Echoping users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose
      "&gt;=net-analyzer/echoping-6.0.2_p434"
    </code>
