UPDATE YOUR GOOGLE CHROME BROWSER NOW – Zero-Day Vulnerability Currently Being Exploited!
iSpeech
The web browser is arguably the most important piece of software on your computer. You spend much of your time online inside a browser: when you search, chat, email, shop, bank, read the news, watch videos and listen to music online, and even do your business/school work, you often do all this using a browser.
Google has released an update for Chrome that patches three security bugs, one of which is a zero-day vulnerability that is currently being exploited. The vulnerability, under the identifier CVE-2020-6418, was discovered by Clement Lecigne, a member of Google's Threat Analysis Group, on February 18.
While it is known that the vulnerability is being exploited in the wild, information on how it is being used is not public yet. The vulnerability has been patched in Chrome version 80.0.3987.122. The update is rolling out to all Windows, Mac, and Linux users. However, it is not known when an update with the patch will make it to the mobile versions of the browser.
As for the vulnerability itself, it is described as a ‘type confusion in V8’. V8 is Chrome’s component responsible for processing JavaScript code. Type confusion refers to a logical bug that occurs when a program accesses resources using an incompatible type, leading to logical errors. The vulnerability, when exploited, can allow attackers to run unrestricted code on the affected applications.

The search giant patched Chrome’s first zero-day vulnerability back in March 2019 when it disclosed the security risk along with a vulnerability in Windows 7. Since the patch fixes a zero-day that is currently being exploited in the wild, it is best for users to update their browsers to the latest version (80.0.3987.122). You can download the update using the online, as well as the offline installer, or head to the three-dot menu on Chrome 🡲 Help 🡲 About Google Chrome, and force the update.
Important to know! The offline installer links do not include the automatic update feature.
