All reports of dbus-policy-excessively-broad for the archive. The extended description of this tag is:
The package contains D-Bus policy configuration that matches broad classes of messages. This will cause strange side-effects, is almost certainly unintended, and is a probable security flaw.
For instance,<policy user="daemon"> <allow send_type="method_call"/> <allow send_destination="com.example.Bees"/> </policy>
in any system bus policy file would allow the daemon user to send any method call to any service, including method calls which are meant to be restricted to root-only for security, such as org.freedesktop.systemd1.Manager.StartTransientUnit. (In addition, it allows that user to send any message to the com.example.Bees service.)
The intended policy for that particular example was probably more like<policy user="daemon"> <allow send_type="method_call" send_destination="com.example.Bees"/> </policy>
which correctly allows method calls to that particular service only.
