Apple Botches iPhone Patching Says Independent Security Evaluators:
$10,000 hack contest winner takes Apple to task over slow iPhone fixes.

Computerworld — Apple Inc. took more than three months to patch an iPhone vulnerability, even though it had technical details of the bug and had crafted a fix for Mac OS X, the researcher who reported the flaw said Tuesday.
"They messed up," said Charlie Miller, an analyst at Independent Security Evaluators (ISE), a Baltimore-based security consultancy, and a noted iPhone and Mac OS X researcher. "For three months, I was walking around with a vulnerable iPhone. They had the vulnerability and the exploit, they understood the exploit because they patched it on Mac OS X, but then they said that they didn't know that [the iPhone] was vulnerable."
The WebKit vulnerability, which Apple patched last Friday as part of the iPhone 2.0 update, was reported to the company in late March after Miller used it to hack a MacBook Air notebook on March 27 during the "PWN to OWN" contest held at the CanSecWest security conference.
Miller traded the vulnerability and his exploit to TippingPoint Technologies Inc.'s Zero Day Initiative (ZDI), the security company's bug bounty program and the contest's sponsor, in exchange for a $10,000 check; TippingPoint immediately reported the vulnerability to Apple. Three weeks later, Apple patched the bug in Safari for Mac OS X by updating the browser to Version 3.1.1.
After CanSecWest, Apple asked Miller through ZDI if the bug was also present in the iPhone's version of Safari. He told Apple that he suspected it was, but he couldn't confirm it because he didn't have a chance to try out his exploit on the device. "I was in Canada at the time," he said, "and I didn't want to rack up roaming charges on my iPhone. The ZDI people didn't think the iPhone was vulnerable, but I wasn't sure."
Miller gave it little thought after that, assuming that Apple—which had been given technical details of the vulnerability and the source code of his exploit—would try the exploit against Safari on the iPhone.
But two weeks ago, after he expressed concern in a story in The Washington Post that Apple hadn't updated the iPhone to fix the vulnerability he'd uncovered, or others that had been patched on Mac OS X since February, Apple sent him an e-mail. "They got all mad, and sent me a nasty e-mail," Miller said. "They said I should have reported this to Apple security rather than to The Washington Post. I told them 'I gave you the exploit, what else do you want me to do?'"
