The ElGamal implementation in Botan through 2.18.1, as used in Thunderbird and other products, 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.
