Systemd sends back an ActivationFailure D-Bus signal if the activation
fails. However, when it receives these signals, dbus-daemon does not
verify that the signal actually came from systemd. A malicious local
user could send repeated ActivationFailure signals in the hope that it
would "win the race" with the genuine signal, causing D-Bus to send back
an error to the client that requested activation.
