We have received an update alert for recent CVE for KB ID 4771, to install a patch. What we want to understand is not in any guide, is - Is this patch just for our Windows VBR server…? Are there any pre reqs. Going through the setup of the .exe from the ISO there are no checks and no reboot required, this was tested installed on a non Veeam server which may not give the correct results…?Thanks in advance Tony

Replying to your question:

Hi @TonyHalligan,

As recommended by Veeam in the KB article shared above, a reboot is required. Kindly plan for a reboot accordingly.
