CVE-2013-3954: The posix_spawn system call in the XNU kernel in Apple Mac OS X 10.8.x does not properly validate the data...

The posix_spawn system call in the XNU kernel in Apple Mac OS X 10.8.x does not properly validate the data for file actions and port actions, which allows local users to (1) cause a denial of service (panic) via a size value that is inconsistent with a header count field, or (2) obtain sensitive information from kernel heap memory via a certain size value in conjunction with a crafted buffer.

Security readout for executives and security teams

CVE-2013-3954 is a local Apple OS X kernel flaw in posix_spawn on Mac OS X 10.8.x. A local user could crash the system or expose sensitive kernel heap memory. This is mainly a risk for legacy Macs or images still running Mountain Lion-era software. Exposure appears limited to Mac OS X 10.8.x systems where untrusted local users or processes can execute code. Modern macOS versions are not identified as affected in the provided bundle. Treat this as a legacy-platform cleanup item unless 10.8.x systems remain in business use. The local-only requirement lowers immediate urgency, but kernel memory disclosure and system crash risk matter on shared or exposed endpoints. Mitigation focus: Identify any Mac OS X 10.8.x systems or legacy images.; Review Apple advisories for the official update path.; Apply applicable Apple security updates or retire unsupported systems..
