Apple blocks Mac OS X security holes
Apple has posted a Mac OS X Security Update that patches almost two dozen holes in the Unix-based operating system. The update incorporates fixes for AirPort, Apple Type Services, Finder, Installer, Security Framework, VPN and a raft of other, under-the-hood apps and utilities.
However, the fix doesn't appear to patch the recently exposed vulnerability  in Mac OS X's Disk Image handling code.
The updates, for client and server versions of Mac OS X, and for PowerPC- and Intel-oriented releases of the operating system, are available from Apple's Support site here , or via the OS' own Software Update utility.
Full details of the fixes are presented here . ®
