Posted on 2021-07-09 by guenni

Windows[German]After installing updates (e.g. KB5004945, KB5003690, KB5004760), some decicated to close the vulnerabilities in the print spooler service, systems with label printers from Zebra and Dymo experienced printing issues – printing is no longer possible.

And then there is the suspicion that Windows 10 gets the updates directly past WSUS, from the Microsoft update servers, no matter what the administrator has set in group policies.

Posted on 2021-07-08 by guenni

[German]Microsoft has released out-of-band security updates for the PrintNightmare vulnerability (CVE-2021-1675) in the Windows Print Spooler service. But these updates seem to end in chaos – it reminds me on the Printer-Gate in March 2021, where Microsoft had to release a series of update fixes to close a printer vulnerability but still allow printing. I'll summarize a few points outside of Microsoft's documentation in this blog post. These range from the fact that the updates don't close the vulnerabilities, to installation issues and problems with Zebra label printers subsequently refusing to print.

Posted on 2021-07-06 by guenni

[German]The Audacity saga continues – as of July 2, 2021, there was another change to the audio application's privacy agreement.
