Apple has released Mac OS X 10.6.8, the latest update to Snow Leopard (and perhaps the last, as OS X 10.7 Lion is due out in July). This update, which is 474 MB, includes a number of security fixes, for such elements as AirPort, the AppStore, Core Graphics, FTP server, and several third-party elements such as MySQL and OpenSSL. Altogether, 40 bugs are fixed in this update. We’d like to highlight a kernel vulnerability, whereby “A null dereference issue existed in the handling of IPV6 socket options. A local user may be able to cause a system reset,” discovered by Intego engineer Thomas Clement.
Apple also updated Mac OS X Server, with a 542 MB updater, to version 10.6.8.
