Description:
Two vulnerabilities were reported in AppKit. A local user can obtain elevated privileges on the target system.
A local user can invoke the NSDocument API with a specially crafted filename to trigger a stack overflow and, on some filesystems, execute arbitrary code on the target system [CVE-2008-0048]. On most filesystems, code execution is not possible.
A local user can also access a mach port in NSApplication and send specially crafted messages to privileged applications in the same bootstrap namespace to cause the target application to execute arbitrary code [CVE-2008-0049].
Mac OS X versions 10.5 and later are not affected by these vulnerabilities.

Impact:
