In parallel with the distribution of Mac OS X 10.5.8, Apple has posted four security updates for its last-generation operating system, Tiger. Two target PowerPC and Intel systems running the core OS. Similarly, the remaining updates address the PowerPC and Universal Binary codebases for Tiger Server.

All of the releases require Mac OS X 10.4.11, and fix flaws which could lead to application crashes, or attacks using malicious code. Many of these involve Trojan programming, specifically in terms of decompressed data, images with ColorSync profiles, and OpenEXR and PNG files. A separate vulnerability has been corrected in format strings for the Login window.
