The Ubuntu security team deemed this advisory irrelevant for Ubuntu:25.04.
NVD Description
Note: Versions mentioned in the description apply only to the upstream avahi package and not the avahi package as distributed by Ubuntu.
A flaw was found in the Avahi-daemon, where it initializes DNS transaction IDs randomly only once at startup, incrementing them sequentially after that. This predictable behavior facilitates DNS spoofing attacks, allowing attackers to guess transaction IDs.
