Apple says the flaw "may allow reading or writing out of the bounds of the allocated heap. By enticing a user to visit a web page containing a maliciously-crafted Java applet, an attacker can trigger the issue which may lead to arbitrary code execution. This update addresses the issue by performing additional bounds checking when creating QTPointerRef objects."
The company generously credits Dino Dai Zovi , TippingPoint and the Zero Day Initiative for reporting the flaw which was discovered eight days ago. The flaw was uncovered at a Hack A Mac event at the CanSecWest security conference in Vancouver, Canada.

- FTPServer Available for: Mac OS X Server v10.4.9. Security Update 2007-004 applied an incorrect ftp configuration file for Mac OS X Server v10.4.9 systems. Users with ftp access, who would normally be restricted to certain directories, may be able to access directories outside the normal scope.
