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

NVD Description

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

avahi-daemon in Avahi through 0.6.32 and 0.7 inadvertently responds to IPv6 unicast queries with source addresses that are not on-link, which allows remote attackers to cause a denial of service (traffic amplification) and may cause information leakage by obtaining potentially sensitive information from the responding device via port-5353 UDP packets. NOTE: this may overlap CVE-2015-2809.
