Description

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 receivers public key, the generator defined by the receivers public key, and the senders ephemeral exponents can lead to a cross-configuration attack against OpenPGP.
