Google addressed four serious security flaws in its Chrome browser prior to the start of its Pwnium 4 contest this week.
The patches were released on Tuesday and each vulnerability was given a “high” risk rating, according to a security bulletin. Three out of the four flaws fetched prizes from Google's bug bounty program, with security researcher Chamal de Silva earning the highest reward – $4,000 – for his discovery of CVE-2014-1700.
Pwnium 4 begins Wednesday at the CanSecWest conference in Vancouver, Canada, and is focused on the Chrome OS. This year's big prize is awarded to whoever can deliver an attack via a web page that can compromise a computer using the Chrome OS even after it reboots.
The total pot for this year's competition is close to $3 million.
