CVE-2025-67603

Firewall policy manipulation via unchecked D-Bus client calls

Published Jan 8, 2026 · Updated Jan 8, 2026

Improper authorization in Foomuuri before 0.31 allows local users to alter firewall zone assignments through its D-Bus service. The privileged fi.foobar.Foomuuri1 service accepts zone-management method calls without Polkit authentication or D-Bus connection restrictions. Any local account, including low-privilege service accounts, can reassign interfaces to zones, weakening firewall policy or causing a limited service interruption.
