Apple has released security updates for Mac OS X Panther 10.3.1 client and server systems and Mac OS X Jaguar 10.2.8 client and server operating systems.

The Panther update includes the following updated components: OpenSSLzlib "gzprintf()" function, an update to the open-source lossless compression library used by Darwin, the kernel of Apple's OS.

The Jaguar update improves a number of components, including document formatting system, groff; Unix macro processor component, gm4; and Mail w/CRAM-MD5 authentication (used to debug common authentication services).

Both updates are available for download from Apple's Web site and through the Software Update feature.
