How to fix?

Upgrade Centos:8 bind-export-libs to version 32:9.11.20-5.el8 or higher.

NVD Description

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

In ISC BIND9 versions BIND 9.11.14 -> 9.11.19, BIND 9.14.9 -> 9.14.12, BIND 9.16.0 -> 9.16.3, BIND Supported Preview Edition 9.11.14-S1 -> 9.11.19-S1: Unless a nameserver is providing authoritative service for one or more zones and at least one zone contains an empty non-terminal entry containing an asterisk ("*") character, this defect cannot be encountered. A would-be attacker who is allowed to change zone content could theoretically introduce such a record in order to exploit this condition to cause denial of service, though we consider the use of this vector unlikely because any such attack would require a significant privilege level and be easily traceable.
