sys/openbsd/stack_protector.c in libc in Apple iOS 6.1.3 and Mac OS X 10.8.x does not properly parse the Apple strings employed in the user-space stack-cookie implementation, which allows local users to bypass cookie randomization by executing a program with a call-path beginning with the stack-guard= substring, as demonstrated by an iOS untethering attack or an attack against a setuid Mac OS X program.

Security readout for executives and security teams

This is a legacy Apple platform weakness in how user-space stack cookies were initialized. A local user could weaken a memory-corruption defense on iOS 6.1.3 or Mac OS X 10.8.x. It is not described as a remote entry point, but it could help another local or chained attack succeed. Exposure is most likely in legacy Apple fleets running iOS 6.1.3 or Mac OS X 10.8.x. Modern supported Apple versions are not identified as affected in the supplied CVE text. Organizations should focus on old devices, lab systems, kiosks, and retained Mac endpoints with local-user access. Prioritize as legacy-risk cleanup, not an emergency internet-facing incident. The main business concern is unsupported Apple systems where local users or chained exploitation could turn this defense bypass into privilege escalation or jailbreak-related compromise. Mitigation focus: Review the cited Apple advisories and support pages for vendor-fixed release guidance.; Upgrade or retire affected legacy iOS and Mac OS X systems where possible.; Limit local account access on any retained affected Mac OS X 10.8.x systems..
