Advisories for Pypi/Qiskit-Terra package

A maliciously crafted QPY file containing 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.

A maliciously crafted QPY file containing a malformed symengine serialization stream as part of the larger QPY serialization of a ParameterExpression object can cause a segfault within the symengine library, allowing an attacker to terminate the hosting process deserializing the QPY payload.
