Google Chrome has over two billion users worldwide and dominates the web browser market. But that also makes it a prime target for hackers, and Google has now issued its fourth urgent upgrade warning in two months.
In a official blog post, Google has revealed that seven security threats rated “high” have been discovered in Chrome, with vulnerabilities affecting Chrome users on all major operating systems: Windows, MacOS, and Linux.
Google currently gives few details on the flaws. This is a common practice as the company tries to limit information to stop the spread of these vulnerabilities to hackers and save time for users to protect themselves. Therefore, that’s all Chrome users need to do for now:
- High – CVE-2021-30598: V8 type confusion. Reported by Manfred Paul
- High – CVE-2021-30599: Confusion of type in V8. Reported by Manfred Paul
- High – CVE-2021-30600: Use after free in printing. Reported by 360 Alpha Lab
- High – CVE-2021-30601: to be used after free in the extensions API. Reported by 360 Alpha Lab
- High – CVE-2021-30602: Use after free in WebRTC. Reported by Cisco Talos
- High – CVE-2021-30603: Course in WebAudio. Reported by Google Project Zero
- High – CVE-2021-30604: Use after free in ANGLE. Reported by SecunologyLab
Historically, all of these have been used by hackers to execute code to gain control of a target’s computer. The most recent zero-day hack in Chrome (where hackers are known to exploit a vulnerability before Google could fix it) was a V8 flaw.
To combat these new threats, all Chrome users must access Settings> Help> About Google Chrome. If your browser version on Linux, macOS, and Windows is listed as 92.0.4515.159 or higher, you are safe. Otherwise, the About screen should prompt you to update and restart your browser. You should do this immediately.
It is to Google’s credit that fixes for high-level attacks are usually released within days of their discovery, but their effectiveness still depends on billions of users updating and restarting their browsers. .
Chrome is a great browser, but attacks are escalating and there have been eight Chrome Zero Day hacks this year. It is now essential to keep Chrome up to date at all times. Go check it out now.
