If you are using the Mozilla Firefox browser, it is strongly advised to check that it has already been updated on your device and that you are already on Firefox 72.0.1 or Firefox ESR 68.4.1. Indeed, Mozilla, the foundation that offers this browser, has just revealed a critical flaw that is corrected with these two versions.

“Incorrect alias information in the IonMonkey JIT compiler to define the array elements can cause type confusion. We are aware of targeted attacks in nature that abuse this flaw, “reads the ad.

The discovery of this flaw is credited to Qihoo 360, a Chinese cybersecurity company.

Update, immediately

The importance of this flaw is such that in the United States, for example, the Department of Homeland Security is asking users and businesses to make the necessary updates.

“Mozilla has released security updates to address a vulnerability in Firefox and Firefox ESR. An attacker could exploit this vulnerability to take control of an affected system. This vulnerability has been detected in exploits in the wild. The Cybersecurity and Infrastructure Security Agency (CISA) encourages users and administrators to review the Mozilla Security Advisory for Firefox 72.0.1 and Firefox ESR 68.4.1 and apply the necessary updates, “said the department.

Normally, on computer, Mozilla Firefox updates itself automatically. However, you can check if you are already on the latest version by clicking on the menu, then Help, then About Firefox.
