Remote Code Execution Vulnerability for Windows Print Spooler which was discovered recently by Microsoft

Many of you must have applied Microsoft recently released Out-of-Band patches for this which are KB5004958 & KB5004954 for Windows Server 2012 R2 , KB5004948 for Windows Server 2016 and KB5004945 for Windows 10 based machines. However, we are also reading articles which mention that the patches released by Microsoft are affecting the functionality of Zebra Printers. With our company having Zebra printers being actively used we have not applied those patches. Any of know if Microsoft have release modified version of patches?

Don’t worry, let’s check the Zebra official document. https://supportcommunity.zebra.com/s/article/000021051?language=en_US
From the document we can see that only printers running Windows 10 versions 21H1, 20H2, or 2004 and Windows Server 20H2 or 2004 may be affected. So you could install updates securely on your servers which run Windows Server 2012 R2 and Windows Server 2016.

Besides, there is a Fix in the document:
