Apple has released a Mac OS X security update, providing patches for a number of very important and critical system security flaws. AppKit is being repaired so that malicious users can't exploit buffer overflows with carefully crafted .rtf and .doc files. The Safari web browser is being updated in order to prevent data being unwillingly sent to another web site. Mail no longer loads remote images when the user tries to print or forward and HTML-formatted message (unless the user gives consent) and Mac OS X's Bluetooth code has also been tweaked to make it more secure.
