Lintian tag information: dbus-policy-excessively-broad (type: error)

Description (from lintian-explain-tags)

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.
