NOTE: the vendor disputes this issue stating that this sequence is not \removing the state that is left by old nodes. At some point the manager obviously stops being able to accept new nodes since it runs out of memory. Given that both for Docker swarm and for Docker Swarmkit nodes are required to provide a secret token (it’s actually the only mode of operation) this means that no adversary can simply join nodes and exhaust manager resources. We can’t do anything about a manager running out of memory and not being able to add new legitimate nodes to the system. This is merely a resource provisioning issue and definitely not a CVE worthy vulnerability.\
