Today, Apple released a new security update for Mac OS X 10.4.8 and Mac OS X 10.4.8 Server. The update fixes security issues with QuickTime for Java and Quartz Composer. Apple gives us the following description about the update:
Description: Java applets may use QuickTime for Java to obtain the images rendered on screen by embedded QuickTime objects and upload them to the originating web site. When this facility is used in conjunction with Quartz Composer, it becomes possible to capture images that may contain local information. This update addresses the issue by disallowing Quartz Composer compositions in unsigned Java applets. Quartz Composer compositions continue to function locally. Applications and signed Java applets that utilize QuickTime and QuickTime for Java are unaffected. This issue does not affect systems prior to Mac OS X v10.4. It also does not affect the Windows platform. Credit to Geoff Beier for reporting this issue.
As usual, the update is available though Software Update and Apple's documentation site.
