Apple releases Mac OS X 10.5.4 update, security fixes

By Katie Marsal

Apple on Monday evening released Mac OS X 10.5.4, the latest significant revision to Leopard and a key part of its online strategy. Also, Security Update 2008-004 and Safari 3.1.2 for Tiger address security issues for earlier Mac OS X versions.The update (59MB for 10.5.3 users) is considered an important precursor to Mac support for MobileMe, Apple's imminent sync and hosting service.

In addition to laying the groundwork for the future replacement for .Mac, the update is also key to fixing a number of major bugs identified since the release of Mac OS X 10.5.3, including an Adobe CS3 corruption bug with remote file saves and a chronic shutdown flaw.

Also mended with the fix are reliability with AirPort when on 5GHz 802.11a and 802.11n networks, iCal stability, access to secure websites with Safari, and a number of fixes for Exposé and Spaces.

Support for additional cameras' RAW photo formats has also been expanded, the company says.

Apple recommends the update for all Leopard users to improve the stability of their systems, and rolls in previous security updates released between Mac OS X 10.5.3 and the new update.

Additionally, the company has released Security Update 2008-004 for Mac OS X Tiger client (Intel, PowerPC) and Tiger Server (Intel, PowerPC) that bring security fixes built into Mac OS X 10.5.4 to the earlier operating systems, including protection against vulnerabilities in significant components such as CoreTypes, the Dock, SMB File Server, Ruby and Webkit.

A third update, Safari 3.1.2 for Mac OS X Tiger, fixes a specific flaw in WebKit (addressed for Leopard in 10.5.4) that would allow malicious JavaScript to either crash Safari or else allow running hostile code through the browser.

The full list of fixes in Mac OS X 10.5.4 follows below:

General

AirPort

iCal

Safari

Spaces and Exposé
