With 99 reported vulnerabilities and patches to both Microsoft browsers, Office and Windows, this month’s Patch Tuesday update is not as large an administrative burden as you might initially think. We’ve rated the browser updates as a “Patch Now” update due to issues with the Chakra engine, but both Office and Windows can be scheduled according to a regular patch cadence. Unfortunately, we have another Adobe Flash update to deploy, but no critical development updates for February.

Known issues

Each month, Microsoft includes a list of known issues that relate to the operating system and platforms included in this update cycle. I have referenced a few key issues that relate to the latest builds from Microsoft including:

  • Microsoft Cluster Shared Volumes (CSV) can still generate the error message,” “STATUS_BAD_IMPERSONATION_LEVEL (0xC00000A5).” Microsoft is still working on a solution. Until a fix is released, you can try the operation as an administrator or try to “own” directories in question before the operation.
  • After installing some Asian language packs you may still (see KB4493509) receive the error, “0x800f0982 – PSFX_E_MATCHING_COMPONENT_NOT_FOUND.”

Microsoft has been working on a fix for both these issues for a while now; we don’t expect a resolution any time soon.

Major revisions

This month, two CVEs have undergone a major revision increment:

  • CVE-2019-1332: CVE information revised to announce the availability of Microsoft SQL Server 2016 for x64-based Systems Service Pack 2 (CU) and Microsoft SQL Server 2016 for x64-based Systems Service Pack 2 (GDR).
  • CVE-2019-8267: Microsoft revised this to include Internet Explorer 11 installed on all supported editions of Windows 10 Version 1809, Windows Server 2019, Windows 10 Version 1903, and Windows 10 Version 1909 because they are affected by this vulnerability. This change may affect your server update cycle

Each month, we break down the update cycle into product families (as defined by Microsoft) with the following basic groupings:
