The posix_spawn system call in the XNU kernel in Apple Mac OS X 10.8.x does not prevent use of the _POSIX_SPAWN_DISABLE_ASLR and _POSIX_SPAWN_ALLOW_DATA_EXEC flags for setuid and setgid programs, which allows local users to bypass intended access restrictions via a wrapper program that calls the posix_spawnattr_setflags function.

Security readout for executives and security teams

This is a legacy Apple OS X kernel issue affecting Mac OS X 10.8.x. A local user could weaken protections around privileged setuid or setgid programs, potentially helping them bypass intended restrictions. It requires local access; the provided sources do not show remote exploitation, active exploitation, CVSS scoring, or a named vendor fix. Exposure is most likely limited to systems still running Apple Mac OS X 10.8.x. Modern fleets are unlikely to be affected unless legacy Macs remain in production, lab, kiosk, or specialized operational roles. Address this when legacy Mac OS X 10.8.x systems exist. The business risk is concentrated in unsupported or unmanaged endpoints where local users can run code. If no such systems remain, document non-exposure and close with low residual concern. Mitigation focus: Check Apple guidance for OS X 10.8.x security updates or migration paths.; Inventory and retire or isolate remaining OS X 10.8.x systems.; Restrict local interactive access on any affected legacy hosts..
