Apple has released its seventh security fix for 2008 that targets a number of flaws since the release of Leopard OS X 10.5, and more recent flaws caused by the OS X 10.5.5 update.

The updater is available for both Mac OS X Leopard on client and server, and for both Mac OS X Tiger on client and server (Intel and Power PC processors supported). The updater addresses problems with the core Mac OS X operating system layer and the powerful Unix operating system hidden inside.

Fixed were things like the launchd daemon, CUPS printing, ColorSync, Finder, networking, Quicklook, root certificates, ClamAV, and Unix features like: Apache, libxslt, MySQL Server, PHP, Postfix, rlogin, Tomcat, and Vim. This is not a complete list, but only highlights.

You can see a complete list of these fixes in Apple Support article HT3216.
