How to fix?

There is no fixed version for Centos:7 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:7 relevant fixed versions and status.

Libgcrypt before 1.6.3 and GnuPG before 1.4.19 does not implement ciphertext blinding for Elgamal decryption, which allows physically proximate attackers to obtain the server's private key by determining factors using crafted ciphertext and the fluctuations in the electromagnetic field during multiplication.
