Last week Adobe released new versions of its Acrobat and Reader products, to address fourteen security vulnerabilities in earlier versions.

In the Adobe product lineup, Acrobat is the commercial PDF builder, while Reader is the free PDF viewer. At one time you pretty much needed to have Reader installed to view PDF files, but these days PDF viewer functionality is increasingly built into operating systems and web browsers.

The new version of Reader — officially referred to as Acrobat Reader DC — is 2020.013.20064. Details are available in the related Adobe Security Bulletin.

All of Adobe’s Acrobat/Reader products update themselves by default, and there’s apparently no simple way to disable that feature. Still, if you have Reader installed, and you use it to view PDF files obtained from email or the web, it’s a good idea to make sure it’s up to date.

To check for updates, start Reader and navigate its menu to Help > Check for Updates... If there’s a newer version available, you’ll be prompted to install it.
