As Microsoft returns from its last summer vacation, we may anticipate a limited number of CVEs to be handled across all OS systems this month.
Extended Security Updates (ESUs) for Windows 7 and Server 2008/2008 R2 are now halfway complete, so anybody using these operating systems should be planning an upgrading strategy.
Also, with the announcement of CVE-2021-40444, we should expect an Internet Explorer upgrade.
If you’re concerned about Adobe Acrobat and Reader, you may rest certain that they’ll be updated soon, according to Adobe’s Prenotification Security Advisory APSB21-55.
So, although this should be a relatively simple September Patch Tuesday, take advantage of it while it lasts since this is the quiet before the storm.
As we all know, software upgrades ramp up around October and November, just before the holidays, and we also have to account for providing support for all of these new operating systems.
