You can apply the Safari 14.1.2 update (fixes Webkit exploit), but there is no patch yet for the PDF exploit. Mojave users: There is currently no path to getting Mojave secure.

If your Mac is managed by CELS Systems, you can follow the instructions below, and we are also working on an update button for the Self Service app, but I wanted to get this announcement out quickly rather than waiting for that to be ready.īig Sur users: The latest patches will fix both PDF and Webkit exploits. MacOS users, please visit Software Update in your System Preferences and ensure you’re up to date. IOS users (iPhone, iPad, Apple Watch), apply all pending updates ASAP. One is via malformed PDFs, and another is through Safari (Apple’s built-in web browser).
