With three zero-days and several serious vulnerabilities in key Windows server and authentication areas, it's time to patch now.

This month's Patch Tuesday release was a big one, and includes fixes for Microsoft browsers and two zero-day vulnerabilities for Windows. Time to get busy updating!

This month's Patch Tuesday brought a solid set of updates for Windows, Microsoft Office, Exchange, and Chromium-based Edge (Chromium). But there weren't any critical issues requiring companies to patch right away.

With this month's very light Patch Tuesday release from Microsoft, security and systems administrators should take time to test their apps and desktop/server builds.

For the first Patch Tuesday of 2022, Microsoft offered up fixes for 97 security issues, with six of them rated as critical.

With 67 flaws addressed, six publicly-reported issues and one vulnerability already exploited, this month's updates pale in comparison to the challenges addressing the Log4j issue.

Microsoft's update for this month brings fixes for four zero-day vulnerabilities and 74 updates to the Windows ecosystem — including a difficult-to-test kernel update and an Exchange Server update that requires some technical skill and due diligence.

For June, Microsoft released 50 updates to address vulnerabilities across the Windows and Office ecosystems. There's some good news — and some bad.
