None of the vulnerabilities fixed in the April Patch Tuesday update from Microsoft fix any of the IE issues reported at the Pwn2own hacking event in March. IE was exploited twice during the Pwn2own 2014 event. Apple’s Safari Web browser, as well as Mozilla’s Firefox, were also exploited during the Pwn2own event. Apple patched Safari for its Pwn2own flaws on April 1 and Mozilla patched Firefox on March 18.
“Microsoft works with the security community to protect our customers against all threats, and we are investigating possible issues identified by researchers during the Pwn2Own competition,” Dustin Childs, group manager for Microsoft Trustworthy Computing, told eWEEK. “We are not aware of any attacks and the issues should not affect our customers, as Pwn2Own organizers do not publicly disclose the competition’s findings.”
