  • Initial impressions of Patch Tuesday, March 2020

    We have 113 new patches in the Microsoft Update Catalog.

    There’s a new Servicing Stack Update for Win10 version 1903 and 1909, KB 4541338. There’s also a new one for Win10 1809 and 1803, and for Win8.1.

    Dustin Childs’s report is up on the ZDI site:

    • 115 separately identified security holes (CVEs)
    • None of them are “Publicly known” or “Exploited.”

    CVE-2020-0852 is his top pick for a notable security hole. It’s a bug in Word that can be triggered if you preview a Word document in Outlook. The offered patches are for Office 2019 Click-to-Run, Mac Office 2016, Office Online Server, and Sharepoint Server 2019. Microsoft categorizes it as “Exploitation less likely.”

    Microsoft hasn’t acknowledged the bugs in the “optional, non-security, C/D Week” patch for Win10 1903 and 1909, released late last month. No idea if this latest drop fixes any of the multitude of problems with KB 4535996. There’s also no mention I can find of the disappearing icon/temporary profile bug that’s been with us for the past month. But there is a humongous list of fixes to 1903 and 1909.

    Notably, the change lists for both Win10 1903 and 1909 are the same.

    No indication that Win10 version 2004 will ship today. I was half-way expecting it.

    UPDATE: Two hours later and I’m not seeing any major cries of pain. Stay tuned.
