Applying the Java Security update on Mac OS X
The recent Java Security update for Mac OS X requires at least 10.6.8. For systems running a version of the OS prior to Mac OS X 10.6.8 that are also encrypted with PGP, the steps listed below are necessary in order to update the system and apply the java security update. More information on how this vulnerability affects Mac OS X can be found at About Flashback Malware.
Step 1. Verify that the most recent PGP client is installed.
Step 2. Update PGPIn order to update your PGP install to the most recent version you will need to download and run the installer. The most recent PGP installer can be found here: PGP for Mac 10.2 MP4.
Once you have finished updating PGP, you will need to restart your machine before proceeding to step 3. Failure to restart will render the system unusable.
Step 3. Update the OSOnce you have verified that your PGP install is Version 10.2.0 [Build 2526], you can download and install the Mac OS X 10.6.8 Combo updater found here: Mac OS X 10.6.8 Combo v. 1.1.
After you have downloaded and installed the Mac OS X update, proceed to step 4.
Step 4. Apply the Security PatchOnce you are running at least Mac OS X 10.6.8, launch Software Update from the Apple menu at the top left of the screen. The update will be called "Java for Mac OS X 10.6 Update 8" for 10.6 users and "Java for OS X Lion 2012-003" for 10.7 users.
The 10.6 version can be downloaded directly here: Java for Mac OS X 10.6 Update 8
The 10.7 version can be downloaded directly here: Java Security Update 2012-003
