Synopsis

The remote PhotonOS host is missing multiple security updates.

Description

An update of the libgcrypt package has been released.

- 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)

Update the affected Linux packages.
