Can the lightning network be subject to DoS attacks due to message flooding?

In the current implementations of the Lightning network protocol (c-lightning, eclair and lnd), is there any check that stops spamming/flooding of channel_announcement, mode_announcement or channel_update messages? Assume that these messages are valid and provable.
