Google fixes four bugs in Chrome Browser

Recently Chrome Browser users got a new update of the browser. The newest build goes by the number 94.0.4606.81 for OS Windows, macOS and Linux. It will be available for the next few weeks for all Chrome Browser users. The update is one of the means for the company to protect its users from recently discovered bugs in the Chrome Browser.

What this time is up with the Chrome Browser?

All four bugs were discovered in the browser versions for Windows, macOS and Linux. These are not zero-day vulnerabilities but they possess high-risk potentials though. Specialists identify as the most dangerous from them the CVE-2021-37977 identification. It is contained in Garbage Collector and can lead to the execution of malicious code. A researcher who asked to remain anonymous received $ 10,000 from Google on reporting the problem.

Another two CVE-2021-37978 and CVE-2021-37979 could potentially create overflows in Blink и WebRTC. Researchers who reported on them also received $ 10,000 from the company. The third one CVE-2021-37980 in Sandbox was considered to be not that serious. Google awarded only $ 3,000 for this one.

“The Stable channel has been updated to 94.0.4606.81 for Windows, Mac and Linux which will roll out over the coming days/weeks. Extended stable channel has also been updated to 94.0.4606.81 for Windows and Mac which will roll out over the coming days/weeks”, announcement on Chrome Releases page says.¹

Google Chrome is under massive zero day attacks this year

The company didn’t make any further announcements indicating no possible exploitation. If you have concerns about your safety, go and check for the latest Chrome Browser update. You can do this by clicking on three vertical dots on the top right side of your browser. After that look for the Settings tab where the About Chrome link should be found. Check the version of your browser. If it’s the one we mentioned above, then everything is fine; if not, click on update.

If the update can be done, keep in mind Chrome Browser must be restarted to make changes take place. Chrome Browser is one of the most widely used programs with more than 2.65 billion users. And you guessed it right it’s quite a lucrative target for criminals around the world.

It’s interesting that Chrome Browser continues to be the target for the ‘Use-After-Free’ (UAF) exploits. In September this year, the browser was targeted with double-digit UAF attacks. And prior to the discoveries of the four bugs, a zero-day UAF flaw was already reported this month. According to recent media reports, Google has already confirmed the 11th zero-day flaw.
