Once a month, near the end of the Patch Tuesday release cycle, the Readiness teams publishes an update on Microsoft related patches, out of band  (OOB) releases and republished CVE vulnerability documentation. This note is intended as a informal brief on recent changes and may reflect a dynamic or rapidly changing situation.

Unfortunately, Microsoft has released new information about an update (CVE-2023-36025) that changes the patch cadence for Windows. This vulnerability in Windows SmartScreen has now been publicly disclosed making this an additional zero-day for Microsoft Windows. Add this update to your “Patch Now” schedule.

For the month of November 2023, this posting will include the following areas:

  • Resolved issues
  • Reported issues
  • Updated CVE entries
  • Scheduled Out-of-band (OOB) releases
  • Links to the Readiness blog

Resolved Issues
The following section describes the latest reported issues with Microsoft updates, their affected platform and their resolution statues/date:

  • KB5031455: The correct default currency might not display or be used in Windows devices which have locale set to Croatia. This can affect applications which retrieve the device’s currency for purchases or other transactions. Microsoft has now published a resolution for this issue.

Reported Issues
We have included a (usually) short list of reported issues with last month’s Patch Tuesday update from Microsoft.  These issues can relate to Microsoft Windows, Office and associated development platforms such .NET and Visual studio:

Scheduled Out-of-Band (OOB) Release
There are no scheduled Out-of-Band releases from Microsoft scheduled for the next few weeks – bringing us up to Patch Tuesday. If there are any urgent releases, the best place to check for further information is the Windows Release Health dashboard.
