How to fix?

There is no fixed version for Centos:8 libgcrypt.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libgcrypt package and not the libgcrypt package as distributed by Centos. See How to fix? for Centos:8 relevant fixed versions and status.

A timing-based side-channel flaw was found in libgcrypt's RSA implementation. This issue may allow a remote attacker to initiate a Bleichenbacher-style attack, which can lead to the decryption of RSA ciphertexts.
