Google Chrome releases URGENT downloadable security update

Google has released a critical update for the Chrome browser that improves its security by patching a zero-day vulnerability that attackers are already exploiting.

The update brings fixes for at least five vulnerabilities, four of which are classified as high risk and one as critical. After the upgrade, your Chrome browser should be running version 96.0.4664.110.

In the latest release notes, Google said that the new version of the Chrome browser is available for Windows, Mac and Linux. This means that the mobile and tablet versions of Chrome Browser will likely not include the zero-day vulnerability, but to be more secure, I recommend you to update the Chrome browser on your Android phone, tablet, iPhone or iPad as soon as possible.

One of the vulnerabilities is classified as critical, which means it needs urgent attention. Google said that this vulnerability – CVE-2021-4102 – affects Chrome's JavaScript engine, which could allow hackers to easily inject and execute malicious code on the targeted computer.

As attackers are already exploiting this vulnerability, your personal data as well as your computer could be at risk, so installing the new Chrome update becomes essential.

Details of the other four vulnerabilities are scarce, but as they are rated "high" in the release notes, they can also be effective in allowing hackers to get into your computer remotely and perhaps access your data without your knowledge. Google generally restricts these vulnerability details until the majority of users have installed the required update.

How to update your Chrome browser

It's a simple process. Just go to the Help or About section of the browser. If an update is available for your machine, Google will automatically download it or give you the option to do the same.

Once the update is downloaded, simply click the Restart button to apply and restart your browser. Be sure to save any unsaved data as restarting the browser will close all windows and tabs.
