Earlier this week, timed to coincide with Microsoft Patch Tuesday, Adobe released new versions of its PDF authoring tool Acrobat, as well as its free PDF viewer, Reader.

The new versions address ten security vulnerabilities in earlier versions. The new version of Acrobat Reader (DC) is 2021.001.20155.

If you have Adobe Reader installed on any of your computers, you should check whether it’s up to date, and install the new version if it’s not. You can do that by running Reader, and navigating its menu to Help > About Adobe Acrobat Reader DC.

You can install the latest version of Reader by navigating its menu to Help > Check for Updates.
