+    <p>
+    IPsec-Tools is a port of KAME's implementation of the IPsec utilities.
+    It contains a collection of network monitoring tools, including racoon,
+    ping, and ping6.
+    </p>
+  </background>
+  <description>
+    <p>
+    The isakmp_info_recv() function in src/racoon/isakmp_inf.c does not
+    always check that DELETE (ISAKMP_NPTYPE_D) and NOTIFY (ISAKMP_NPTYPE_N)
+    packets are encrypted.
+    </p>
+  </description>
+  <impact type="normal">
+    <p>
+    A remote attacker could send a specially crafted IPsec message to one
+    of the two peers during the beginning of phase 1, resulting in the
+    termination of the IPsec exchange.
+    </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-0.6.7"</code>
