How to fix?

There is no fixed version for RHEL:8 dnsmasq-utils.

NVD Description

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

A flaw was found in dnsmasq. The TFTP server can serve the wrong file contents because a recently used transfer cache is not invalidated when a transfer finishes. An attacker on the local network who can request a TFTP file may cause a later client to receive previously cached data instead of the requested file. In PXE network-boot environments this can substitute attacker-chosen boot content for a victim machine.
