Summary

Updated libgcrypt packages fix security vulnerability

Details

The updated packages fix a security vulnerability:

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 (CVE-2021-40528).
