Now that Mac OS X 10.4 (Tiger) has gone on sale, Apple has released a huge update for Panther, Mac OS X 10.3.9. This includes patching 20 security holes, including several that lend themselves to remote exploitation.

The Security Update 2005-005, which patches both Mac OS X 10.3.9 and Mac OS X Server 10.3.9, covers operating system components ranging from Bluetooth short-range wireless to how the Mac handles TIFF image files.

Danish security firm Secunia rated the vulnerability package as "Highly critical," its second-from-the-top warning, and noted that the grab bag included spoofing, system access (both remote and local), and unauthorized data access flaws.
