Any plans for Samba fix for CVE-2017-7494 ?
I posted elsewhere about this, but CVE-2017-7494 NEEDs to be patched on any device still in operation, and I think that includes the older, technically out of support models that I have 6 of. Wit...
Legacy Sparc, x86 and ARM firmware is now available:
RAIDiator-4.1.16 (Sparc)
We've built firmware with the patch for CVE-2017-7494 for legacy models as well. Once they have undergone QA testing, I believe we plan to release those updates as well
Do you have an ETA?
As for SMB2 and SMB3, we're not updating to a newer samba series on the legacy models at this time so SMB2 support would remain experimental and remain disabled. The new firmware has the same samba version except with the patch so the netgearx at the end (where x is a number) would be incremented by one to reflect the change.
Does it mean that on my Readynas NV+v2 there is a buried disabled SMB2 I can enable by myself in some way via Putty? Can you point me to some helpful resource to do it? Side effects? Thank you
Does this effectively render the NV+ / Duo obsolete if CIFS ( SMB) is required?
NFS & AFP are both not an option for me.

I would argue, that yes, the lack of bringing these devices up to SMB2 or better effectively makes them obsolete. I have disabled SMB1 on all my Windows devices, as MS has recommended, and therefore they can no longer communicate with 5 of my 6 ReadyNAS devices, because only one of them is modern enough to be able to run OS 6. Those same devices also cannot support drives larger than 2TB and, to me, that also leaves them being obsoleted. Your mileage will vary, but my decision on these matters was to go with a different vendor for my NAS needs, where I have a 12 bay unit that gets weekly [security] updates and is able to run SMB 3.
I've done a little research about trying to get an alternate OS into the legacy NASes, but that currently doesn't seem very possible. I really wish, if Netgear no longer wishes to support these devices, they would open source the necessary components so that the FOSS community could take over and provide support.

I read the question as being Has the CVE been addressed on legacy NAS like the NV+ and Duo? The answer to that question is yes.
There are other questions one could ask:
Is it safe to run an NV+ or Duo v1?
In my opinion, yes. And I still do have both deployed as a backup NAS.
The way I read MS recommendation: (a) install their security fix for SMB-1 on all your windows systems (b) remove SMB1 if equipment on your network doesn't need it as an additional security precaution.
SMB-1 remains vulnerable to man-in-the-middle attacks, so I do agree that disabling it is a worthwhile precaution. But on a home network you should be ok as long as you don't allow SMB traffic (port 445) in through your home router - which is a bad idea anyway. FWIW, Wannacry didn't use a MITM attack.
Are the NV+ or Duo v1 competitive with newer NAS?
Clearly not. They are based on a 2006 hardware design, and were replaced about 6 years ago by newer ReadyNAS. They weren't competitive in 2011, and the performance gap has only grown.
Competitive or not, I currently have several Duo's that are unaccessable now, even after updating the FW to v 4.1.16.
Coming in to work and discovering that all of my Netgear NASes are permanently inaccessible was a pretty big shock. Refusing to enable SMB-2 so that I could transfer to a new device is also quite jarring.
I really liked my Duo's - but now I am looking at other vendors.
