    <p>GnuTLS is an Open Source implementation of the TLS and SSL protocols.</p>

      properly.

  <impact type="low">
    <p>A remote attacker could entice a user to connect to a malicious TLS
      endpoint using an application linked against GnuTLS, 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 GnuTLS users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=net-libs/gnutls-3.6.15"
    </code>
