Publication date: 06 Oct 2021
Type: security
Affected Mageia releases: 8
CVE: CVE-2021-40530

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.
