Both Mozilla and US government office CISA have given security warnings concerning Firefox 72 and Firefox ESR after hackers found and abused a vulnerability in the browser. It appears the vulnerability exists in IonMonkey Firefox’s just-in-time compiler, something that is intended to accelerate the JavaScript execution.

Hackers were effectively abusing a “type confusion” vulnerability which is one of the more typical kinds of security deficiencies associated with browsers. These vulnerabilities can be used and abused in various manners, crashing PCs or to fool users into installing malware software, for instance.

Mozilla hasn’t yet confirmed the full details of the specific vulnerability so we don’t really know the particular nuances of the bug. It is encouraging users to update their web browsers as quickly as possible to avoid further issues.

“We know about attacks abusing this flaw in the code”, Mozilla has stated, stressing just how vital it is that you update the browser asap. As per the warning itself, QiHoo 360 ATA, a Chinese web security firm, was the first to discover and reveal the bug to the public. This isn’t the first occasion when Mozilla has been hit by security problems. In June 2019 the company prompted users to update their browsers following a zero-day security flaw. This was a security fault that hackers had figured out how to detect and abuse while it was still unpatched.

To ensure that you are using the most recent version of Mozilla Firefox, go to the menu while the browser is open and hit the assistance button. Next, hit ‘About Firefox’ to open up another window. From here, Firefox ought to do practically everything for you, checking for updates and consequently download and install. When it’s done installing the update you will have to restart the browser.

Stuck in the process? Mozilla has a helpful guide for refreshes here.
