+  <background>
+    <p>The RPCBind utility is a server that converts RPC program numbers into
+      universal addresses.
+    </p>
+    
+    <p>Libtirpc is a port of Suns Transport-Independent RPC library to Linux.</p>
+  </background>
+  <description>
+    <p>It was found that due to the way RPCBind uses libtirpc (libntirpc), a
+      memory leak can occur when parsing specially crafted XDR messages.
+    </p>
+  </description>
+  <impact type="normal">
+    <p>A remote attacker could send thousands of messages to RPCBind, 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 RPCBind users should upgrade to the latest version:</p>
+    
+    <code>
+      # emerge --sync
+      # emerge --ask --oneshot --verbose "&gt;=net-nds/rpcbind-0.2.4-r"
+    </code>
+    
+    <p>All Libtirpc users should upgrade to the latest version:</p>
