They "have been confirmed by the vendor, which, in the Apple case, almost always means that the company has released a patch."
This means that you can find the details on Apples security pages : [docs.info.apple.com...] . Please note, that many of these issues are actually in third party products that Apple bundles in either the client or the server version of the OS and thus not directly the responsibility of Apple or a fault of Apple's. Also, for the third party products, this means that the issue is present in every *nix system that bundles these products. This fact leads to an inflation of security reports where the same issues has a tendency to be reported for each and every instance of eg Linux when there's actually only one bug. If you take a look at the Symantec Security Advisories [symantec.com] there's not one instance of a time critical security issue that's contributed to Apple. On the other hand there are, however, several that are of issue to Mac OS X due to the bundling issue (eg. Apache, Sendmail).
