Today heise reports that Apple's newest MacOS version "Leopard" contains a security hole which had already been fixed over a year ago in an older MacOS version.

First the firewall with holes big as barn doors, now this. Apple says they take security seriously. But it does not look like they're following a defined, stringent secure development process.

It will be interesting to see how Apple will react in the next months and compare that with Microsoft's reaction to the same problem a few years ago.
