There is no fixed version for RHEL:8 unbound-libs.

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 RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

The DNS protocol in RFC 1035 and updates allows remote attackers to cause a denial of service (resource consumption) by arranging for DNS queries to be accumulated for seconds, such that responses are later sent in a pulsing burst (which can be considered traffic amplification in some cases), aka the "DNSBomb" issue.
