Apple has released its fifth Mac OS X security update of 2007 to patch a number of potential vulnerabilities. Security Update 2007-005 makes changes to CoreGraphics, iChat, VPN, BIND, crontabs, PPP, and other components, in most cases correcting problems that require either local user access or access to the Mac via a local network. However, several fixes are more important. An update to BIND prevents a possible remote denial of service attack (but because it reportedly overwrites the BIND launchd plist file, it may both turn BIND off and cause other changes to be lost, a potential problem for Mac OS X Server machines), a new version of fetchmail prevents possible disclosure of passwords, and a fix for CoreGraphics in Mac OS X 10.4 provides additional verification of PDF files to avoid possible crashes when opening maliciously crafted PDFs. The update is available via Software Update or for download in four varieties: for Mac OS X 10.4.9 as Universal (29.2 MB) and PowerPC (15.7 MB) installers; and for Mac OS X 10.3.9 Client (42.5 MB) and Server (56 MB) systems.
Option-click to Hide Apps Quickly
This trick has been available in the Mac OS for years, but many people still don't know it. If you have too many windows cluttering up your screen, you can hide specific ones easily as you work. When you're in any application, hold down the Option key and click on another app's window, on the Dock, or in the Finder to switch to that other app and simultaneously hide all the windows in the previously current app.
