Apple Patches 48 Vulnerabilities in Safari

Apple's latest version of its Safari browser patches a record 48 vulnerabilities, Computerworld reports. The browser shipped the same day as Apple unveiled the iPhone 4 at its annual Worldwide Developers Conference.

Included in the patched vulnerabilities is one that a pair of hackers exploited in March to win a $15,000 prize. Vincenzo Iozzo and Ralf-Philipp Weinmann used a vulnerability in WebKit to hack an Apple iPhone 3GS at the Pwn2Own contest.

More than half the vulnerabilities are labeled with the company's "arbitrary code execution" phrase, meaning the flaws are critical and could be exploited to compromise a Mac or a Windows machine.
