Apple Releases Security Updates for Mac OS X 10.5 Leopard
Bringing Mac OS X 10.5 Leopard up to speed with its more recent big cat siblings, Apple has issued Leopard Security Update 2012-003 and a Flashback Removal Security Update, the latter of which provides a tool for excising the most common variants of the infamous Flashback malware. Previously, Apple had released versions of the Flashback malware removal tool for 10.7 Lion and 10.6 Snow Leopard (see “Apple Releases Flashback Malware Removal Tools,” 12 April 2012).
After installing the Flashback Removal Security Update, the removal tool will run automatically in the background. If the Flashback malware is found, you’ll be notified via a dialog that it has been removed. In some instances, however, you may need to restart your computer to remove the malware completely. Additionally, the Flashback security update disables the Java plug-in for Safari, preventing unintentional use of Java applets in the Web browser.
The Leopard Security Update 2012-003 mirrors the recent release of Safari for 10.7 Lion and 10.6 Snow Leopard (see “Apple Hardens Security with Mac OS X 10.7.4 and Safari 5.1.7,” 9 May 2012), which disables elderly versions of Adobe Flash (10.1.102.64 or older) that are incapable of updating themselves to the current version. If you are running an older version, you’ll be redirected to download and install a current release from Adobe’s Web site.
Both security updates should appear in Software Update, but they can also be downloaded via Apple’s support Web site. The Leopard Security Update 2012-003 weighs in at 1.11 MB, while the Flashback Removal Security Update comes in at 1.23 MB. Both require an Intel-based Mac running Mac OS X 10.5.8.
The security update seems to be for Intel Macs only.
Right. That was a little confusing; nothing in Software Update on a PPC machine, and the downloaded update just refused to install. Could have had a more helpful message.
Not too surprising; a lot of attacks are instruction-set dependent. Another reason, gone now, that Macs have been less vulnerable to attack via these cross-platform mechanisms (Java, Flash, etc).
Same result on my PPC G5
Information on Apple's site does say these 10.5 updates are Intel only: http://support.apple.com/kb/HT1222
But it should have been mentioned in the article since Mac OS 10.5.8 runs on BOTH PPC and Intel Macs. Looks like the author assumed it only ran on Intel.
Apologies to all. The article has been updated to reflect the requirement.
Thanks folks. In Agen's defense, the only place Apple says anything about these updates running only on Intel-based Macs is in the security-related articles, not in the description of the updates or on the download pages.
LOL! So even Apple forgets that Leopard runs on PPC. Well, my G5 iMac power supply has died, so I'm coming over to The Dark Side and getting an Intel machine.
