The new year is already more than a month old. What does that mean for Android? Another year full of vulnerabilities and patches. This month there's a good mixture of issues marked Critical and High, and nothing should come as a surprise (as we've grown used to certain components being affected). Nonetheless, anyone with a mind for security will want to know what's happening to the Android platform—and the security bulletin du jour.

Before we dive into what's included with this month's Android Security Bulletin, it's always good to know what security release is installed on your device. To my surprise, my daily driver, a Pixel 3, is running a security patch that is one month out of date (Jan 5, 2018).

To find out what patch level you are running, open Settings and go to About Phone. If you're using Android Pie, that location changed to Settings | Security & Location | Security updated. Scroll down and tap the version of Android found on your device. The resulting window (Figure A) will reveal your security patch level.

The Pixel devices should be as up to date as possible.

And now, onto the issues.
