Microsoft on Tuesday patched the last vulnerability in Internet Explorer (IE) used by a researcher in March to win $15,000 at the annual Pwn2Own hacking contest.
The company had patched IE twice before to quash bugs exploited by Stephen Fewer of Harmony Security to bring down IE8 on Windows 7 at Pwn2Own. For his efforts, Fewer was awarded a cash prize of $15,000 and a Sony notebook.
Fewer chained three exploits, each for a different vulnerability, to bypass IE's sandbox, called "Protected Mode," and compromise IE8. Pwn2Own sponsor HP TippingPoint called the feat "impressive" at the time.
Microsoft patched the third IE bug in a multiple-flaw update to its browser, part of a 13-bulletin collection.
