By default, your Internet browser will update automatically. Update Chrome on Mac and Windows. Typically, Google updates the Chrome browser automatically on your computer. It happens in the background when you close and opens the browser.

- In all, Google has had to patch five zero-day vulnerabilities within the last three weeks, but users don’t appear to have been affected in any meaningful way as of yet.
- If you want to check and see if your Chrome browser is up to date on Windows, Mac, or Linux, type chrome://settings/help into the address bar and you can see what version of the browser you are currently running.
It’s never a bad time to make sure that all your software is updated in order to keep yourself safe from any potential issues or exploits that might have been discovered in a previous version. Sometimes the situation is far more serious though, and the developers behind your apps discover a bug that needs to be addressed as soon as possible. That’s the case with Google Chrome this week, as two zero-day exploits have just been patched.
On Wednesday, November 11th, Google rolled out a stable channel update for the desktop version of Chrome on Windows, Mac, and Linux addressing two high-severity vulnerabilities being called CVE-2020-16013 and CVE-2020-16017. You should be on version 86.0.4240.198 of Chrome, which you can check by typing chrome://settings/help in the address bar. Chrome should update automatically, at which point you can relaunch to finish updating.

As explained by Threatpost, CVE-2020-16017 as a “use-after-free in site isolation” bug, which an attacker can exploit by creating a webpage, leading an unaware user to that webpage, triggering an error, and executing the code on the victim’s system. CVE-2020-16013 is an “inappropriate implementation in V8” bug, which leads to the software failing to implement or incorrectly implementing one or more security checks. V8 is a component which handles JavaScript and WebAssembly, and attackers can use the same method described above to exploit it.
Whether or not any of us were at risk of having our systems taken over or our data stolen is unclear, but the fact is that these are just two of five zero-day exploits that Google has had to patch in Chrome within the last three weeks. The good news is that Google’s security researchers are finding these exploits about as quickly as they are being discovered by bad actors, but it appears that the hacking community is more aggressive as of late.
Most importantly, this just serves as another reminder that you shouldn’t put off updating your software when a new update drops. Yes, there will occasionally be problems that will need to be addressed in a subsequent update, but the next zero-day exploit could be one that ends with you having important data stolen.

There are plenty of things you can do to keep yourself safe while browsing the internet, and near the top of that list is making sure that all your apps and programs are up-to-date. For example, Google rolled out Chrome 90 to the stable channel for Windows, Mac, and Linux on April 14th with dozens of security fixes, but less than a week later, another update has arrived that everyone who uses Google’s browser should install as soon as possible.
As Chrome’s technical program manager Srinivas Sista revealed in a blog post, Chrome version 90.0.4430.85 comes with seven security fixes, one of which addresses a zero-day vulnerability that Google says has been exploited in the wild. The zero-day is referred to as CVE-2021-21224, and Google describes it as “Type Confusion in V8.” As Google explains, “V8 is Google’s open source high-performance JavaScript and WebAssembly engine.”

Sista goes on to highlight five crucial fixes that have been included in the Chrome version 90.0.4430.85 update:
- CVE-2021-21222: Heap buffer overflow in V8. Reported by Guang Gong of Alpha Lab, Qihoo 360
- CVE-2021-21223: Integer overflow in Mojo. Reported by Guang Gong of Alpha Lab, Qihoo 360
- CVE-2021-21224: Type Confusion in V8. Reported by Jose Martinez (tr0y4) from VerSprite Inc.
- CVE-2021-21225: Out of bounds memory access in V8. Reported by Brendon Tiszka (@btiszka)
- CVE-2021-21226: Use after free in navigation. Reported by Brendon Tiszka (@btiszka)
Chrome doesn’t always apply the latest updates when you open the browser, so if you want to check and see which version you’re running, go to Settings and then click About Chrome at the bottom of the menu bar on the left side of the screen. If you’re already running the latest version of Chrome, you’re good to go, but otherwise, you should begin the process of updating. Once it’s downloaded, click the Relaunch button to finish updating.
Patching dangerous exploits is just one of many reasons to update to Chrome 90. As we reported previously, the update also defaults to HTTPS for most typed navigations, which improves privacy and speeds up loading times for websites that support the protocol. Most sites that you visit use HTTPS, but for those that don’t, Chrome will still fall back to HTTP when and if the HTTPS attempt fails, so you can still visit those sites.
Additionally, Chrome 90 introduced a new Search Tabs button at the top of the browser that has been a monumental addition for those of us who spend all day opening, closing, rearranging, and sorting through browser tabs. The feature is poised to get even better in the near future as well, as Google is testing a “recently closed tabs” section on the Chrome Canary browser that would make it easier to find tabs you accidentally X’d out of.
