While the iPhone 3G and Snow Leopard grabbed everyone's attention at the Worldwide Developers Conference last week, Apple also released security and bug-fix updates to QuickTime, iMovie '08, and iDVD '08.

QuickTime 7.5 tackles several security issues dealing with maliciously crafted media: PICT images, AAC-encoded media, and Indeo video. It also changes the behavior of handling URLs by revealing files in the Finder or Windows Explorer instead of launching them. (For more information on recent QuickTime security issues and how Apple is addressing them, see "QuickTime Security Enhanced with Anti-Exploitation Technologies," 2008-04-23.)

QuickTime 7.5 is available via Software Update or as stand-alone downloads for the following operating systems: Mac OS X 10.5 Leopard (56 MB), Mac OS X 10.4 Tiger (52.8 MB), Mac OS X 10.3 Panther (51.39 MB), and Windows XP and Vista (22.67 MB).

Apple's updates for iMovie and iDVD only state that each addresses "general compatibility issues, improves overall stability, and addresses a number of other minor issues." They're also available via Software Update (once QuickTime 7.5, which is required, is installed), or as stand-alone downloads: iMovie 7.1.2 (17.9 MB) and iDVD 7.0.2 (20.27 MB). They also require Mac OS X 10.4.11 or later.
