Description OSIDB Bzimport 2024-11-15 08:58:22 UTC 
This vulnerability exposes Avahi-daemon to potential DNS spoofing attacks by using a fixed source port for queries. However, the impact is limited because it only affects wide-area DNS and can be mitigated by forwarding queries to local DNS resolvers (e.g., systemd-resolved), which provide better randomization. The impact is primarily on systems actively using wide-area DNS, with .local mDNS being unaffected.
