An update for libgcrypt is now available for openEuler-20.03-LTS-SP1 and openEuler-20.03-LTS-SP2 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2021-1362 Final 1.0 1.0 2021-09-30 Initial 2021-09-30 2021-09-30 openEuler SA Tool V1.0 2021-09-30 libgcrypt security update An update for libgcrypt is now available for openEuler-20.03-LTS-SP1 and openEuler-20.03-LTS-SP2. 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) An update for libgcrypt is now available for openEuler-20.03-LTS-SP1 and openEuler-20.03-LTS-SP2. openEuler Security has rated this update as having a security impact of medium.
