Mozilla earlier today released Firefox 67.0.3 and Firefox
ESR 60.7.1 versions to patch a critical zero-day vulnerability in the browsing software that hackers have been found exploiting in the wild.
Discovered and reported by Samuel Groß, a cybersecurity researcher at Google Project Zero, the vulnerability could allow attackers to remotely execute arbitrary code on machines running vulnerable Firefox versions and take full control of them.
The vulnerability, identified as CVE-2019-11707, affects anyone who uses Firefox on desktop (Windows, macOS, and Linux) — whereas, Firefox for Android, iOS, and Amazon Fire TV are not affected.
At the time of writing, neither the researcher nor Mozilla has yet released any further technical details or proof-of-concept for this flaw.
Through Firefox automatically installs latest updates and activate new version after a restart, users are still advised to ensure they are running the latest Firefox 67.0.3 and Firefox (Extended Support Release) 60.7.1 or later.
