Also pending Red Hat security review for whether this deserves a CVE
(presumably either both issues, or neither, will have a CVE)
Both CVEs have now been assigned:
CVE-2019-14850 - denial of service due to premature .open, depending on
plugin used
CVE-2019-14851 - denial of service due to assertion after NBD_OPT_INFO,
independent of plugin
