How to fix?

Upgrade Debian:unstable avahi to version 0.6.23-3 or higher.

NVD Description

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

The originates_from_local_legacy_unicast_socket function (avahi-core/server.c) in avahi-daemon in Avahi before 0.6.24 allows remote attackers to cause a denial of service (crash) via a crafted mDNS packet with a source port of 0, which triggers an assertion failure.
