There is a warning out about a potentially very serious security vulnerability in OS X. The vulnerability would allow a Trojan Horse to gain root access without the need for user authentication. The good news is that the vulnerability is easily patched. The bad news is that Apple doesn't feel that it is a problem that they have to deal with.
