Through the company’s bug bounty program this round of patches paid $17,000 to researchers, one of the largest pay-outs yet. Much like June’s update, a researcher named Miaubiz found the most flaws in Chrome this time through, reporting eight of them to Google for a total of $7,500.

$3000 was awarded to Sergey Glazunov for cross-origin script injection bug and the cross-origin violation in base URI handling bug, among others. The Russian researcher was the first to receive Google’s “elite” $3,133.7 bounty after reporting a critical “stale pointer” flaw in January.
