Patch Tuesday August 2025 - Two Zero Days and Large Number of Critical Updates

Welcome to my August Patch Tuesday newsletter. Today Microsoft released 107 updates and an additional 25 in the past month for a total of 132 updates.

We have two zero-days to look at. One from today's release of updates and another big one from the previous 30 days.

First is CVE-2025-53779 released today. This Elevation of Privilege vulnerability is rated moderate. Microsoft reports that this relative path traversal in Windows Kerberos allows an authorized attacker to elevate privileges over the network. Microsoft says exploitation is less likely. Due to the fact this exploit is publicly disclosed, I still recommend this gets updated ASAP.

Next is CVE-2025-53770 which was released on July 19. Most likely you have already heard about this in the news since it received widespread coverage last month. This critical rated Remote Code Execution affects the flavors of SharePoint listed in the chart below. Keep in mind that SharePoint Online is not affected. As of the latest update from Microsoft on August 6th, this exploit is still being detected in the wild. If you have enabled the AMSI integration feature and use Microsoft Defender across your SharePoint farm servers then you are already protected from this vulnerability.

Besides this one, there are another 22 updates that are rated "Critical". I've highlighted these in bold in the chart below.

So, we do have a good bit of updating that needs to be done. You will want to download, update and reboot those systems. See you next month!

NOTE: Did you receive an email from me earlier today that appeared to be cutoff? Some of our webinar invitees reported this issue. I also see that a large number of you did indeed register for the webinar so I think that this "bug" only affected a small number of you. If you did receive the cutoff email, you can read more about the webinar and register for it here.

Happy patching!

So, without further ado, here’s the chart of MS patches that affect Windows platforms in the past month.
