+  </description>
+  <impact type="normal">
+    <p>Side-channel attacks can leak private key information. A separate
+      critical bug allows an attacker who obtains 4640 bits from the RNG to
+      trivially predict the next 160 bits of output.

+  <workaround>
+    <p>There is no known workaround at this time.</p>
