Apple on Monday patched 56 vulnerabilities, most of them critical flaws that could be used to hijack machines. Among the fixes was one for a vulnerability that four-time Pwn2Own winner Charlie Miller didn’t get a chance to use at the contest. More than a dozen of the bugs can be exploited by “drive-by” attacks that execute as soon as a victim browses to a malicious Web site. The update to Mac OS X 10.6.7 and the separate 2011-001 security update for Leopard can be downloaded at the Apple site.”]
