An issue was discovered in certain Apple products. iOS before 10.3.2 is affected. macOS before 10.12.5 is affected. The issue involves the "Security" component. A race condition allows attackers to bypass intended entitlement restrictions for sending XPC messages via a crafted app.
The product contains a concurrent code sequence that requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence operating concurrently.
