Hi All,
I hope you're well and keeping safe.
I have a question please related to an Exchange Server 2016 which sits on a Windows Server 2016 Datacenter Edition (x64) machine.
I'm trying to apply the patches for Print Nightmare vulnerability CVE-2021-34527 and I couldn't get installed any of the below patches:
July 7, 2021—KB5004948
July 13, 2021—KB5004238
July 29, 2021—KB5005393
August 10, 2021—KB5005043
The error message that I get is that patches are not applicable for the system.
When I use the "Check for updates" feature, there are no missing updates, I have also tried to reset the Windows Update component and that didn't made any difference.
Could you please advise if the Security Update For Exchange Server 2016 CU21 (KB5004779) (CVE-2021-31196) (CVE-2021-31206) (CVE-2021-33768) includes the mitigation for Print Nightmare CVE-2021-34527, I couldn't see that is clearly mentioned that?
Thank you in advance for your help and time.
