Description

Updated libcryptopp packages fix security vulnerability

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.
