Video: Microsoft responds to Pwn2Own IE hack

Just moments after researchers from VUPEN used two zero-day vulnerabilities to hack into the Internet Explorer 9 browser, I caught up with Mike Reavey, senior director in the Microsoft Security Response Center (MSRC) to get his response to the attack and some information on what happens next.

Apple patches Pwn2Own iPhone OS vulnerabilities

Apple has released a critical update for its flagship iOS mobile operating system to fix several gaping security holes, including a few that were used in successful exploits at this year’s CanSecWest Pwn2Own contest.

The new iOS 4.3.2 software update, which is available for download via iTunes, provides cover for five documented security problems, including vulnerabilities exploited by Charlie Miller (iPhone) and a team of researchers who broke into RIM’s BlackBerry smartphone.

The raw details:

  • QuickLook: A memory corruption issue existed in QuickLook’s handling of Microsoft Office files. Viewing a maliciously crafted Microsoft Office file may lead to an unexpected application termination or arbitrary code execution.

  • WebKit: An integer overflow issue existed in the handling of nodesets. Visiting a maliciously crafted website may lead to an unexpected application termination or arbitrary code execution.

  • WebKit: A use after free issue existed in the handling of text nodes. Visiting a maliciously crafted website may lead to an unexpected application termination or arbitrary code execution. Credit to Vupen Security working with TippingPoint’s Zero Day Initiative, and Martin Barbella.

The iOS update also fixes the Comodo certificate trust policy problem that allowed an attacker with a privileged network position to intercept user credentials or other sensitive information.   This issue was also fixed in separate Safari and Mac OS X updates.
