Apple’s iTunes 11.2.1 update for OS X has been hit by a security blunder. The bug affects all versions of OS X 10.6 (Snow Leopard), 10.7, 10.8 (Mountain Lion) and 10.9 (Mavericks) The bug applies only to iTunes on OS X, but iTunes on Windows is not affected. The bad side of this bug is that you would quite reasonably expect this sort of fault to show up in testing. The good side, if bugs can have good sides, is that Apple fixed it very quickly.”]
