Apple Patches Mac OS X Security Holes

By Geoff Duncan March 2, 2006

Apple Computer has released Security Update 2006-001 for its Mac OS X operating system, patching problems recently exploited by both the Leap.A/Oompa-Loompa worm and the recent shell script exploit which could effect both Apple’s Safari Web browser and Mail applications. Security Update 2006-001 is available for both Mac OS X 10.4.5 (Tiger) and 10.3.9 (Panther) via Mac OS X’s built-in Software Update application as well as Apple’s software support download site. Apple recommends the update for all Mac OS X users.

Security Update 2006-001 patches the recently uncovered shell script exploit by performing additional validation of downloaded files and either warning the user of suspect files (Mac OS X 10.4.5) or refusing to open the downloaded item (Mac OS X 10.3.9). Apple also patched download validation in Mail and its iChat instant messaging program to warn users of unknown or unsafe file types, even if the file’s true nature has been deliberately disguised.

The update also includes important updates to Safari and FileVault, as well as under-the-hood functions in Directory Services, rsync, LibSystem, BOM (Mac OS X’s de-archiving system), and important security updates to perl and PHP (relevant only to users running Mac OS X as an Internet server: the capabilities are disabled by default).

The download ranges in size from roughly 12.5 to 39 MB, depending on the version of Mac OS X being updated (client or server), and separate versions are available for PowerPC-based and newer Intel-based Macs.

Report: Apple’s 2024 MacBooks may face some serious shortages

Apple's John Ternus stands next to an image of the 15-inch MacBook Air at Apple's Worldwide Developers Conference (WWDC) in June 2023.

Looking forward to getting a new MacBook in the next year or so? You might have to wait longer than expected, as Apple chip supplier TSMC is reportedly struggling to get enough skilled workers for its forthcoming Arizona factory. That could mean we see serious shortages of Apple laptops and a struggle to get hold of stock.

The bad news comes from The Wall Street Journal. According to the outlet, TSMC has said that “people with expertise erecting semiconductor facilities were in short supply in the U.S.” As a result, the Arizona factory “would miss its target of starting mass production next year.”

macOS Sonoma public beta review: more than just screensavers

Craig Federighi introducing macOS Sonoma at Apple's Worldwide Developers Conference (WWDC) in June 2023.

It’s that time of year again when Apple launches all of its new operating systems into public beta and invites a brave public to sift through bugs and crashes to find the nuggets of gold that Apple has been working on. With macOS Sonoma now in public beta, the big question is this: should you upgrade your Mac?

Well, this year’s update has been a rather modest one, with few truly standout features. After all, you know it’s an unexceptional update when Apple leads its list of new features in macOS Sonoma with screen savers.
