Privilege escalation in Apple GarageBand before 10.4.9 allows local users to gain root privileges through a malicious app. The affected code inadequately validates a requesting process's entitlement and Team ID before granting privileged access. Exploitation requires a malicious app to run locally, and successful abuse grants root-level control.
