XNU 1228.9.59 and earlier on Apple Mac OS X 10.5.6 and earlier does not properly restrict interaction between user space and the HFS IOCTL handler, which allows local users to overwrite kernel memory and gain privileges by attaching an HFS+ disk image and performing certain steps involving HFS_GET_BOOT_INFO fcntl calls.

Security readout for executives and security teams

This is an old local privilege escalation in Apple Mac OS X 10.5.6 and earlier. A person with local access could abuse HFS+ disk image handling to overwrite kernel memory and gain higher privileges. It is not described as remotely exploitable. Exposure is most likely limited to legacy Apple Mac OS X 10.5.6 or earlier systems, especially where local users can log in or run code. Modern macOS versions are not identified in the provided source bundle. Prioritize remediation if any legacy Mac OS X 10.5.6 or earlier systems remain in business use. The issue requires local access, but successful exploitation could give full system privileges. Mitigation focus: Identify and retire or isolate Mac OS X 10.5.6 and earlier systems.; Apply Apple security updates referenced by HT3757 and APPLE-SA-2009-08-05-1.; Limit local shell, desktop, and code execution access on affected hosts..
