"Browser Zero Day: Update Your Firefox Right Now!"

Researchers have found a flaw in Firefox 72 just two days after it was released.  The issue researchers identified is called CVE-2019-17026. CVE-2019-17026 is a type confusion bug affecting Firefox’s IonMonkey JavaScript Just-in-Time (JIT) compiler. The JIT compiler takes JavaScript source code and converts it to executable computer code for the JavaScript to run directly inside Firefox as if it were a built-in part of the app. The problem is fixed, and Firefox urges users to download the newest update to fix the issue.
