Description

The ElGamal implementation in Crypto++ through 8.5 allows plaintext recovery

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.
