How to fix?

Upgrade Centos:8 unbound-libs to version 0:1.7.3-10.el8 or higher.

NVD Description

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

Unbound 1.6.4 through 1.9.4 contain a vulnerability in the ipsec module that can cause shell code execution after receiving a specially crafted answer. This issue can only be triggered if unbound was compiled with --enable-ipsecmod support, and ipsecmod is enabled and used in the configuration.
