Thank you very much, all

Hello,
As it was reported yesterday by Tom's Guide (read the article here https://www.tomsguide.com/us/smart-home-security-despair-rsa2019,news-29601.html ), there is a Telnet vulnerability in Reolink cameras which allows full control of the camera including installation of cryptocurrency-mining malware.

"Alex "Jay" Balan of Bitdefender showed RSA attendees that four different cheap Chinese security cameras sold under the Geenker, Keekoon, Reolink and Tenvis names had terrible security. Most could be accessed over the internet via Telnet, the 1970s network protocol with no encryption. Anyone with mid-level coding skills could dial into the cameras from anywhere and watch you at home. (UPDATE: Reolink reached out to us to say it had patched the flaws with a firmware update.)"

The article mentions that Reolink has patched the flaws with an update. What is the current situation with the installed firmware? For example, I have multiple RLC-420 and RLC-422-5MP cameras. What version of firmware should I have to make sure the security vulnerability is addressed? Thank you.
