Firefox Update

Indian government cybersecurity agency– The Indian Computer Emergency Response Team (CERT-In)- has issued a high-level warning for those using Mozilla Firefox to browse the internet. CERT-In said that several security vulnerabilities have been found in Mozilla products which could be used by hackers to bypass security restrictions, conduct spoofing attacks, execute arbitrary code, obtain sensitive information and cause denial of service attacks on the targeted system.

All Mozilla Firefox internet browser versions before the latest Firefox 98 are affected by these security vulnerabilities. Also, ESR versions prior to 91.7 and Mozilla Firefox Thunderbird versions prior to 91.7 are facing similar security vulnerabilities. CERT-In is warning users to upgrade to Mozilla Firefox version Firefox 98, Firefox ESR 91.7and Thunderbird 91.7 immediately.

The CERT-In advisory reads, “Out-of-Bounds Read Vulnerability in Mozilla Firefox ( CVE-2020-6821 ). This vulnerability exists in Mozilla Firefox due to a boundary condition when using the WebGLcopyTexSubImage method. A remote attacker could exploit this vulnerability by specially crafted web pages. Successful exploitation of this vulnerability could allow a remote attacker to disclose sensitive information.”

According to Homeland Security’s National Cyber Awareness System, a major vulnerability has been found in Firefox which can allow an attacker to completely take over a user’s computer system, whether on Windows or Mac-based systems. The alert from the Department of Homeland Security is encouraging users to review the Mozilla Foundation Security Advisory 2020-03, which directly addresses the vulnerabilities.

Now the question is how hackers are trapping users? According to the Indian Computer Emergency Response Team, hackers are forcing users to click on certain websites or links. Once inside, they are crossing the security fence and put their hands on personal information. So it is recommended to update the browser to keep the information safe. So let’s quickly learn how to update Mozilla Firefox.

To update your copy of the Mozilla Firefox version:

  • On a Mac: Launch Firefox and click About > Firefox and click the “Restart to update Firefox” button to update Firefox
  • On a PC: Launch Firefox and go under either Options > Firefox Updates or Options > Advanced > Update or Help > About Firefox and click the “Restart to update Firefox” to update Firefox.
