Summary
libgcrypt security update
Details

Libgcrypt is a general purpose cryptographic library originally based on code from GnuPG.

Security Fix(es):

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)
