This Month’s Patch Tuesday Brings Fixes for 11 Actively Exploited Vulnerabilities

By Bill Toulas / June 9, 2021

Microsoft has released the June 2021 “Patch Tuesday” for its various products. The notable aspect this month is that the pack contains fixes for eleven vulnerabilities currently under active exploitation. As such, applying the patch is a tad bit more critical than usual, although there’s really no Tuesday Patch that system administrators can afford to skip or even postpone. In total, Microsoft has fixed 49 flaws, with five of them being critical and the rest classified as important.

Here are the most important critical fixes of this month:

And below are the currently-exploited flaws that are rated as “important”:

Although the classification of the flaws is definitely a critical factor to consider, it is often indicative of the damage potential that a particular exploit could have. This month, we see five important bugs being actively exploited. This indicates that even small holes are important to address as they can open up the potential for other, more serious exploits. Some of these zero-days are used in chained exploits, so no matter if a bug is rated as critical or just important, if adversaries are using it, there’s a good reason to fix it.

Before you apply this month’s update, make sure to backup your data and secure your most important files from unfortunate events like a corrupted filesystem. Remember, this is rare, but it can happen, so don’t skip the backing-up part.

Adobe has synchronized the fixing of critical flaws on its products too, so if you’re using the Reader, Photoshop, Connect, and the Creative Cloud in general, you should apply the available updates there too.
