Out-of-Band Security Update for Windows 8.1, Windows RT 8.1, and Windows Server

[Corrine]

Microsoft has released Out-of-Band security update KB4578013* addressing CVE-2020-1530 and CVE-2020-1537 which could allow attackers to gain elevated privileges after successful exploitation.

There are no prerequisites for the update and a restart is not required. To get the standalone package for this update, go to the Microsoft Update Catalog website.

Note: The August 11, 2020 security update addressed the vulnerabilities for all other supported operating systems.

I just installed the update on my Win8.1 HP Stream7 tablet, and (at least, in my case) a reboot WAS required.

EDIT:   I see that KB4578013 was apparently installed at the same time... perhaps that's what required the reboot?

No, I inadvertently used the link from the Windows Update History page and edited my original post.  KB4578013 is the correct KB number and that pages states a restart isn't required.

KB article: "You do not have to restart your device after you apply this update."

WU: "Restart your PC to finish installing updates"

On two different server installations (I've installed it on so far). This is the only update I applied. <sigh />
