Apple Security Update Reissued After First Breaks 64-bit Apps

The new update, dubbed "2005-007 v1.1," replaces the original rolled out Monday, and can be downloaded from Apple's site or from within the vulnerable 10.4.2 (Tiger) operating system.

Software developer Wolfram Research notified users of its Mathematica 5.2 program, one of the first 64-bit applications available for the Mac, that "due to an error on the part of Apple, [the original] update prevents any 64-bit-native application from running. In particular, this means that Mathematica 5.2 will not run on any G5 system if it has installed the Security Update."

Apple fixed the problem, which was caused by the omission of a 64-bit version of the LibSystem component.

Both the client and server editions of 10.4.2 should be updated to 1.1 if the earlier security fixes have been applied, Apple said. Mac OS X 10.3.9, which was also updated Monday, was not affected by the forgetfulness flaw.

The security update issued this week was Apple's largest ever, and patched more than 40 different bugs in some of the operating systems most important components and bundled applications.
