  <title>IPSec Tools: Denial of service</title>
  <synopsis>
    Multiple errors in the IPSec Tools racoon daemon might allow remote
    attackers to cause a Denial of Service.

  <background>
    <p>
    The IPSec Tools are a port of KAME's IPsec utilities to the Linux-2.6
    IPsec implementation. They include racoon, an Internet Key Exchange
    daemon for automatically keying IPsec connections.
    </p>
  </background>
  <description>
    <p>
    The following vulnerabilities have been found in the racoon daemon as
    shipped with IPSec Tools:
    </p>
    <ul>
    <li>Neil Kettle reported that
    racoon/isakmp_frag.c is prone to a null-pointer dereference
    (CVE-2009-1574).</li>
    <li>Multiple memory leaks exist in (1) the
    eay_check_x509sign() function in racoon/crypto_openssl.c and (2)
    racoon/nattraversal.c (CVE-2009-1632).</li>
    </ul>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could send specially crafted fragmented ISAKMP
    packets without a payload or exploit vectors related to X.509
    certificate authentication and NAT traversal, possibly resulting in a
    crash of the racoon daemon.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All IPSec Tools users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=net-firewall/ipsec-tools-0.7.2"</code>
  </resolution>
