A Major Vulnerability Detected in Mozilla Firefox

Mozilla asked all users to bring their browsers to the latest version of Firefox. This is due to a security problem caused by a vulnerability in the ‘Just-in-time’ compiler.

Mozilla has made an important announcement concerning Firefox users. The announcement prompted users to upgrade Firefox to the latest version, with a major vulnerability being cited as the reason for this.

The vulnerability, found by Chinese security company Qihoo 360, is in Firefox’s’just-in-time’ (JIT) compiler. The JIT compiler’s task is to improve JavaScript performance so that websites can load faster. The vulnerability found is causing the malicious JavaScript to be operated externally in the host computer’s browser.

In practice, this is how it works: Any attacker can lure the user of their choice to a site that operates malicious JavaScript code and trap it and infiltrate its victim’s computer. Qihoo, however, did not give specific information as to how the vulnerability was used, who the attackers were or who were targeted.

Vulnerabilities in scanners are one of the most important issues in the security community. It explains, it is often used quietly and unwittingly users to place malware or ransomware. Scanners are also the target of government surveillance vehicles.

Vulnerabilities in scanners are being used by government intelligence agencies to apprehend spies and criminals. In security circles, governmentactivities are frowned upon because vulnerabilities that intelligence agencies do not report to software developers can also be used for malicious activities.

The U.S. Department of Homeland Security’s cyber alert unit also issued a security alert, asking users to upgrade their browsers to Firefox 72.0.1. The latest version says the vulnerability has been eliminated. While little is said about the deficit, only’control of the affected system can be taken over’. Finally, you can visit the Settings section of the browser to update your Firefox browser to the latest version.
