Apple this week released updates to Mac OS X, patching a total of 51 security flaws.

"Both Mac OS X 10.7, aka Lion, and 10.6, better known as Snow Leopard, were updated with fixes," writes Computerworld's Gregg Keizer. "The two operating systems were last updated in mid-October 2011."

"Of the 51 total flaws, 40 were tagged by Apple with its usual 'arbitrary code execution' phrase, the company's way of saying that the bugs were critical and could be used by attackers to hijack a Mac with a working exploit," Keizer writes.
