FYI this vulnerability appears to have been previously mentioned (and discussed) in the following thread from late May…
https://community.wd.com/t/samba-vulnerability-discovered-actually-not-wds-fault/206408
It is unknown if WD patched the vulnerabilities previously mentioned in other threads unrelated to the CVE-2017-7494. And considering how long it took WD to issue an update after being notified of those past vulnerabilities expect to wait four or more months for an update that might (or might not) fix CVE-2017-7494.
