Description

The remote Rocky Linux 8 host has packages installed that are affected by a vulnerability as referenced in the RLSA-2022:5311 advisory.

- The ElGamal implementation in Libgcrypt before 1.9.4 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.
