PrintNightmare, the zero-day hole in Windows – here’s what to doīriefly put, Microsoft published a Windows Print Spooler patch for a bug dubbed CVE-2021-1675, as part of the June 2021 Patch Tuesday update that came out on.

ICYMI, PrintNightmare is an aptly named bug that became a public danger for the unfortunate reason that a team of security researchers jumped to an incorrect conclusion:

Here’s the bad news: early reports suggest that the patch doesn’t protect against all aspects of the PrintNightmare bug, and that it may be possible to bypass the patch entirely, depending on the version of Windows involved and the Print Spooler configuration on the targeted computer. (This month, that’s, which is still almost a week away.) In Windows update parlance, OOB refers to patches that are deemed so important that they can’t wait until the next official Patch Tuesday, which is always the second Tuesday in each calendar month. OOB is a jargon term that refers to communications that are kept separate from the usual channel you use, notably for safety reasons in case the main channel should fail or need overriding in an emergency. The patch is what Redmond refers to as an OOB Security Update, where OOB is short for out-of-band. Here’s the good news: Microsoft has released an emergency patch for the infamous PrintNightmare bug that was revealed in the Windows Print Spooler just over a week ago.
