What is CVE-2021-35958?

A vulnerability exists in TensorFlow's Keras utility, specifically in the method tf.keras.utils.get_file, which allows attackers to overwrite arbitrary files when extracting crafted archives. This arises when the extraction feature is used with untrusted archive sources. This behavior raises concerns for applications relying on this function, particularly in scenarios where unverified archives may be processed.
