Security researchers from around the world apparently turned their attention to Adobe’s Acrobat and Acrobat Reader recently, and their efforts revealed a big pile of new vulnerabilities. Adobe responded yesterday, releasing new versions of its Acrobat-related products that address eighty-six of those vulnerabilities.
Although Acrobat and Reader exist in several different forms, the one most people actually use these days is Adobe Acrobat Reader DC (Continuous), and the latest version of that variant is 2019.008.20071.
If you use any paid version of Acrobat, or any of its free Reader variants, you should update it as soon as possible. This is particularly important if you open PDF files with uncertain provenance on the web or received in email. If you use Reader as a browser plug-in or extension, you should drop everything and update immediately.
Recent versions of Acrobat and Reader include an automatic update system, so your install may already be up to date. The easiest way to find out is to run it, then navigate its menu to
Check for Updates... If an update is available, you’ll be able to install it from there.
