The second and final day of Pwn2Own 2014 saw successful attempts by seven entrants against five products, with $450,000 paid to researchers. This brings the two-day payout total to $850,000, not including charitable donations or the value of the laptops, ZDI points, and other prizes given to winning researchers.
The following vulnerabilities were successfully presented on Thursday in the Pwn2Own competition:
By an anonymous participant:
Against Google Chrome, an arbitrary read/write bug with a sandbox bypass resulting in code execution. Upon review, contest judges declared this a partial win due to one portion of the presentation’s collision with a vulnerability presented earlier at Pwnium.
By Sebastian Apelt and Andreas Schmidt:
Against Microsoft Internet Explorer, two use-after-free bugs and a kernel bug, resulting in system calculator.
By Liang Chen of Keen Team:
Against Apple Safari, a heap overflow along with a sandbox bypass, resulting in code execution.
By George Hotz:
Against Mozilla Firefox, an out-of-bound read/write resulting in code execution.
By Team VUPEN:
Against Google Chrome, a use-after-free affecting both Blink and WebKit along with a sandbox bypass, resulting in code execution.
By Zeguang Zhao of team509 and Liang Chen of Keen Team:
Against Adobe Flash, a heap overflow with a sandbox bypass, resulting in code execution.
All vulnerabilities were disclosed to their respective vendors in the Chamber of Disclosures, and each will be working to address those issues through their respective processes.
Thanks to all participants; we look forward to seeing everyone again next year.
