Of these external disclosures, $21,000 was paid in bounties, with the amount for the other 11 disclosures still being determined.  The highest bounty was paid to Pinkie Pie, the well known Chrome hacker who won Google’s Pwnium competition in 2012, for discovering a vulnerability that led to sandbox escape in PPAPI. As a general rule, the Chrome Team does not disclose details of the security bugs fixed in their releases, so there is not much more detail.
