Overview
Affected versions of this package are vulnerable to Heap-based Buffer Overflow via stale register allocations left over after register allocation. An attacker can trigger the exception handler, which causes the code generator to use stale register state and fail to load correct values from spill slots. This can lead to incorrect execution behavior and potential downstream impact.
