+            <unaffected range="ge">1.3.2</unaffected>

+    <background>
+        <p>Libtirpc is a port of Sun&#39;s Transport-Independent RPC library to Linux.</p>
+    </background>
+    <description>
+        <p>Currently svc_run does not handle poll timeout and rendezvous_request
+does not handle EMFILE error returned from accept(2 as it used to.
+These two missing functionality were removed by commit b2c9430f46c4.
+
+The effect of not handling poll timeout allows idle TCP conections
+to remain ESTABLISHED indefinitely. When the number of connections
+reaches the limit of the open file descriptors (ulimit -n) then
+accept(2) fails with EMFILE. Since there is no handling of EMFILE
+error this causes svc_run() to get in a tight loop calling accept(2).
+This resulting in the RPC service of svc_run is being down, it&#39;s
+no longer able to service any requests.
+
+Due to a lack of handling of certain error cases, connections to Libtirpc could remain ESTABLISHED indefinitely.</p>

+    <impact type="normal">
+        <p>Denial of service can be achieved via establishing enough connections to Libtirpc to reach the limit of open file descriptors for the process.</p>
+    </impact>
+    <workaround>
+        <p>There is no known workaround at this time.</p>
+    </workaround>
+    <resolution>
+        <p>All Libtirpc users should upgrade to the latest version:</p>
+        
+        <code>
+          # emerge --sync
+          # emerge --ask --oneshot --verbose ">=net-libs/libtirpc-1.3.2"
+        </code>
