On June 15th, Apple released a CRITICAL security update for Java. This patch fixes a long-term, SERIOUS SECURITY FLAW in Java which allows a remote hacker to control your computer if you launch a Java-based application on the Web. Many sites use Java, including PSU’s own WebCT / Blackboard course management system and Banner, so it is imperative that you apply the update as soon as possible. Additionally, the update seems to fail on many OS X 10.5 computers the first time it is run, so you may need to follow the steps below two or three times. If you encounter any problems, please contact the Helpdesk at x5-2929 to arrange for a Desktop Support service call.
1) Go to the Apple menu in the top left corner of the screen.
2) Select Software Update.
3) Make sure that either of the following updates are checked, and proceed to install them.
* Java for Mac OS X 10.4, Release 9
* Java for Mac OS X 10.5 Update 4
4) The machine will prompt for a reboot to complete the update. If you receive an error message stating that the update failed, repeat the above steps. If you continue to encounter problems, please call the Helpdesk.
Please do not allow this vulnerability to remain unpatched, as it poses a serious threat to data security on campus. If you would like more information on this patch, please visit the following links:
