Google security researchers shared more information on four security vulnerabilities, also known as zero-days, unknown before they discovered them being exploited in the wild earlier this year.

The four security flaws were found by Google Threat Analysis Group (TAG) and Google Project Zero researchers after spotting exploits abusing zero-day in Google Chrome, Internet Explorer, and WebKit, the engine used by Apple's Safari web browser.
