If you really didn’t feel like shelling out 30 bucks for Snow Leopard, you may want to open Software Update, because Apple has just released Security Update 2009-005 for Tiger and Leopard. The fun thing about reading the notes for security updates is that you suddenly realize how many different ways hackers could nuke your computer, pre-update of course. In this specific one, they talk about CUPS printer driver, PHP, mySQL, CoreGraphics, and even ClamAV antivirus exploits.

The update is live, so download away.
