+	  <p>The ElGamal implementation in Crypto++ through 8.5 allows plaintext
+	    recovery because, during interaction between two cryptographic
+	    libraries, a certain dangerous combination of the prime defined by
+	    the receiver's public key, the generator defined by the receiver's
+	    public key, and the sender's ephemeral exponents can lead to a
+	    cross-configuration attack against OpenPGP.</p>
