Qiskit allows arbitrary code execution decoding QPY format versions < 13

Impact

A maliciously crafted QPY file can potentially execute arbitrary-code embedded in the payload without privilege escalation when deserializing QPY formats < 13. A python process calling Qiskit's qiskit.qpy.load() function could potentially execute any arbitrary Python code embedded in the correct place in the binary file as part of a specially constructed payload.

Patches

Fixed in Qiskit 1.4.2 and in Qiskit 2.0.0rc2
