Mozilla and Google have already patched the critical Firefox and Chrome vulnerabilities exploited recently by white hat hackers at a competition in China.
The flaw was fixed with the release of Firefox 82.0.3, Firefox ESR 78.4.1 and Thunderbird 78.4.2 just a couple of days after it was disclosed at the 2020 Tianfu Cup International PWN Contest, which took place over the past weekend in China.
As for the Chrome vulnerability disclosed at the Tianfu Cup, it's tracked as CVE-2020-16016 and it has been described by Google as an inappropriate implementation issue in the base component.
For the Firefox vulnerability they earned $40,000, while for the Chrome flaw, which allowed them to achieve remote code execution with a sandbox escape, they received $100,000.
One of the Qihoo 360 researchers earned $20,000 from Google earlier this year for a sandbox escape vulnerability affecting Chrome.
