Apple Plugs Vulnerabilities in Panther, Jaguar:
"The software updates a number of libraries, services and programs, including Personal File Sharing and QuickTime for Java. While described as the Security Update 2003-11-19 for Jaguar 10.2.8, the update is also recommended for Mac OS X 10.3, called Panther through Apple's automatic Software Update program. "

The update comes after Apple in October had been criticized for fixing some security problems in Mac OS X within its latest Panther release but not providing patches for earlier versions of the operating system. Later, the company indicated that it planned to offer patches for Jaguar.
