    Multiple vulnerabilities have been discovered in Openswan:
    </p>
    <ul>
    <li>Gerd v. Egidy reported a NULL pointer dereference in the Dead Peer
    Detection of the pluto IKE daemon as included in Openswan
    (CVE-2009-0790).</li>
    <li>The Orange Labs vulnerability research team
    discovered multiple vulnerabilities in the ASN.1 parser
    (CVE-2009-2185).</li>
    </ul>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could exploit these vulnerabilities by sending
    specially crafted R_U_THERE or R_U_THERE_ACK packets, or a specially
    crafted X.509 certificate containing a malicious Relative Distinguished
    Name (RDN), UTCTIME string or GENERALIZEDTIME string to cause a Denial
    of Service of the pluto IKE daemon.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Openswan users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=net-misc/openswan-2.4.15"</code>
