Google Chrome Browser Vulnerable To Huge Zero-Day Security Exploit, Update Now
It appears to be an issue with memory management as it relates to a part of Chrome called FileReader, which allows developers to issues pop-up menus. Chrome updates itself automatically, though if you leave your PC and browser running all the time, you may see a little green icon alerting you that a browser restart is required to apply the update. Or you might already be patched. You can check for updates by clicking on the three vertical dots in the browser's upper-right corner and navigating to Help > About Google Chrome. As of this writing, the latest Stable build is 72.0.3636.121.
