    <p>GnuTLS is an Open Source implementation of the TLS 1.2 and SSL 3.0
      protocols.
    </p>

  <description>
    <p>Multiple vulnerabilities have been discovered in GnuTLS. Please review
      the CVE identifiers and Lucky Thirteen research paper referenced below
      for details.
    </p>
  </description>
  <impact type="normal">
    <p>A remote attacker could sent a specially crafted packet to cause a
      Denial of Service condition. Additionally, a remote attacker could
      perform man-in-the-middle attacks to recover plaintext data.
    </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-2.12.23-r1"
