In total, there are nine zero-day vulnerabilities listed in the recent round of patch notes. Of the four being actively exploited, PrintNightmare remains the pack leader in notoriety due to the numerous stories surrounding it, including reports of how it had official patches thatdidn’t effectively do their jobsand caused certain printers not to work. Third parties stepped up to provide their own patches for the PrintNightmare situation. However, given that it’s typically advisable to rely on Microsoft to deliver Windows-related fixes, many waited on Redmond to produce an official patch that didn’t introduce more issues than solutions.
