Overview
Affected versions of this package are vulnerable to Race Condition within a Thread via the Data Flow Graph node cloning process in the DFG optimization component. An attacker can cause a process crash by processing maliciously crafted web content that triggers loop unrolling optimizations where mutable data structures are incorrectly shared between original and cloned nodes, leading to inconsistent state when subsequent optimization phases modify the shared data.
