CVE-2019-14850 nbdkit: denial of service due to premature opening of back-end connection
An attacker, by connecting to nbdkit’s TCP port, is able to make the current plugin’s .open() callback run. For some plugins this callback
does a considerable amount of work, for example connecting to a remote machine (nbdkit-ssh-plugin) or launching a small VM (nbdkit-guestfs-plugin). Thus for a small amount of work done by the attacker (opening many TCP connections but not sending any data), a large amount of work is done by nbdkit (eg. making many full ssh connections to a remote machine or launching hundreds of VMs).
A related problem is that if nbdkit is configured to use TLS for client authentication, even clients which are not authorized are able to attack nbdkit in this way because all they h
