Apple released the same update for users of both Mac OS X Tiger and Panther, as two separate downloads, available as usual through Apple's Software Update program or as a standalone installer. Most significantly, the update fixes 41 vulnerabilities, many of which could allow a remote attacker to execute malicious code on the affected system. The affected software includes the Adobe Flash Player Plug-in, AppleRAID, the Mach Kernel, the Safari Web browser, and other core system components.
Among other issues, the update also brings Apple's Safari browser to version 3.0, previously available to Leopard users or those who downloaded the software separately. It also adds RAW image decoding support for several cameras, including the Panasonic Lumix DMC-FZ50, the Leica V-Lux 1, the Olympus E-400, the Olympus EVOLT E410, the Olympus EVOLT E510, and the Canon EOS 40D. Finally, it improves compatibility when using OpenType fonts in QuarkExpress, reliability when using VMware's Fusion, and synchronization between iPhone and Yahoo address books.
