The notes appear within content security published in the Apple support page, including these vulnerabilities is an issue of state management in the directory dyld that has to do with the launch of the app, a bug in the validation camp management metadata with the kernel, and a bug in the sandbox profile that allowed apps to run arbitrary binary.
