How to fix?

Upgrade Centos:7 libgcrypt to version 0:1.5.3-13.el7_3.1 or higher.

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.

The mixing functions in the random number generator in Libgcrypt before 1.5.6, 1.6.x before 1.6.6, and 1.7.x before 1.7.3 and GnuPG before 1.4.21 make it easier for attackers to obtain the values of 160 bits by leveraging knowledge of the previous 4640 bits.
