Mozilla, U.S. Government Urges Firefox Users To Update

Those using the popular Mozilla Firefox web browser should update immediately, warns a new U.S. Department of Homeland Security alert. According to the Cybersecurity and Infrastructure Security Agency within DHS, Mozilla last week released security updates to address a vulnerability in Firefox, Firefox ESR and Thunderbird that could allow an attacker to take control of an affected system. The agency said users and administrators should review Mozilla’s security advisories for Firefox 72.0.1, Firefox ESR 68.4. and Thunderbird 68.4.1. On Jan. 8, Mozilla announced the update that would fix the security flaws, saying the company was aware of targeted attacks in the wild. The update was labeled as “critical.” “Incorrect alias information in IonMonkey JIT compiler for setting array elements could lead to a type confusion,” the company said. “We are aware of targeted attacks in the wild abusing this flaw.”
