How do these vulnerabilities work?
A user-after-free security vulnerability is basically a memory-corruption flaw that allows modification or corruption of memory data, allowing a hacker to take control of an affected software or system. All that the remote attackers need to do, is to escalate privileges on your Chrome web browser by convincing you to click and visit a malicious website. This instantly allows attackers to run malicious code on your affected system while bypassing any sandbox protections.
How can you protect yourself?
The use-after-free vulnerability has been existing in the wild for quite some time now and is one of the most commonly discovered vulnerabilities. Thus, the chances of it reappearing in frequent periods are high.
Thankfully, Google has already released an update for this new Chrome version, to patch this active zero-day vulnerability and the stable channel has been updated to 78.0.3904.87. So now, all you need to do is to Click on the update arrow visible at the top-right corner of Chrome browser. Once you have successfully updated to the latest version of Chrome across your desktop and mobile, you will become safe from these vulnerabilities.
Such security bugs and vulnerabilities are bound to appear and reappear from time to time. It is for this reason that Quick Heal strongly recommends that you keep your web browser and security products up-to-date and follow best security practices for optimum defense against the rising/evolving threats and zero-day vulnerabilities.
