0x0

Update May 10: This post was originally posted on May 09

I spoke too soon when I reported yesterday that Google had confirmed a relatively rare update only for Android users of the Chrome browser. Windows, Linux and Mac users can no longer breathe easy and should now check that their Chrome browsers are updated as soon as possible. Why the change? Because Google has now confirmed that billions of users of the most popular web browser on the planet are affected by the latest security vulnerabilities.

In a May 10 announcement from Prudhvikumar Bommana of the Google Chrome team, it was confirmed that the same nine vulnerabilities that prompted the Android security update warning also applies to desktop browser on all platforms. In fact, there are 13 security patches in total, as I originally reported, but only nine have received CVE numbers. It’s currently unknown why there was a delay between confirming the two updates, but I’ll try to find out and report back. While none of the disclosed vulnerabilities this time around are zero-day, meaning there’s no evidence that attackers are already exploiting them, that’s no reason to be complacent. So please update your Chrome browser as soon as you can.

In the case of the desktop browser, this means heading to the Help | About your Google Chrome menu. The update will automatically start downloading if available. the full details can be found here but the most important thing to remember is to restart the browser or the update will not be activated. The updated version that includes security fixes in the desktop client is 101.0.4951.64.

Users of other Chromium-powered web browsers such as Brave and Edge should also be aware that security updates will likely follow in the coming days. I’ll update this article as soon as I can confirm these updates have rolled out, with instructions on what you should do. Of course, Chrome for Android users should also make sure the app is updated, as below.

Update to Google Chrome v101.0.4951.61 as soon as you can

As usual, the Forbes Straight Talking Cyber ​​advice is to ensure that your smartphone is updated as soon as possible so that vulnerability fixes can be applied. Google said the fix is ​​rolling out and should be available on Google Play “in the coming days.” The updated version, according to Google’s announcement, is Chrome v101.0.4951.61 for Android. As of this writing, my Samsung Galaxy Note 10+ is still on the April 26th update of v101.0.4951.41 and therefore is not yet patched.

How to check your Google Chrome for Android version number

The best advice is to let Google update your app as soon as it’s available. To set this up, access the three-dot menu in the Google Play app and head to Settings | Network Preferences Auto-update apps.
