GHSA-89V8-RHWQ-HF77 asteval has a Sandbox Escape via BaseException Subclasses

Summary An attacker who can supply expressions to asteval.Interpreter.eval can raise SystemExit, KeyboardInterrupt, GeneratorExit, or BaseException from inside the sandbox. These exceptions are subclasses of BaseException but not Exception, so they bypass the except Exception: safety net in both...
