影響: pip:pylint < 4.0.9 → 4.0.9
Since 2006 / pylint 0.15.2, pylint caches its stats as pickles in PYLINT_HOME and reload them on the next run with pickle.load. Someone without access to the configuration or linted code, but with access to the cache directory (predictable PYLINT_HOME on a multi-user host) can write a crafted pickle that will runs arbitrary code when pylint access its stat cache. Patches From pylint 4.0.9, the result cache is now stored as JSON instead of pickle, preventing code-execution. Workarounds Until upg…
