CVE-2020-26267: In affected versions of TensorFlow the tf.raw_ops.DataFormatVecPermute API does not validate the src_format and dst_form

CVE-2020-26267 is a vulnerability in TensorFlow where the tf.raw_ops.DataFormatVecPermute API (a function for converting data format layout) fails to check the src_format and dst_format inputs, leading to uninitialized memory accesses (using memory that hasn't been set to a known value), out-of-bounds reads (accessing data outside intended boundaries), and potential crashes. The vulnerability was patched across multiple TensorFlow versions.
