Apple released today a Security Update 2008-001 for MacOS X 10.4 fixing 5 vulnerabilities in one patch.

At the same time an upgrade to Mac OS X 10.5.2 was released, which also incorporates the security update all in one package (fixing 8 vulnerabilities). An upgrade like this can be best compared to a Service Pack in the windows world. It's not just a security fix, but also a functionality upgrade.
