+Subject: [PATCH] bus: Implement GDBusAuthObserver callback
+
+ibus uses a GDBusServer with G_DBUS_SERVER_FLAGS_AUTHENTICATION_ALLOW_ANONYMOUS,
+and doesn't set a GDBusAuthObserver, which allows anyone who can connect
+to its AF_UNIX socket to authenticate and be authorized to send method calls.
+It also seems to use an abstract AF_UNIX socket, which does not have
+filesystem permissions, so the practical effect might be that a local
+attacker can connect to another user's ibus service and make arbitrary
+method calls.
