CVE-2020-15196: In Tensorflow version 2.3.0, the `SparseCountSparseOutput` and `RaggedCountSparseOutput` implementations don't validate

TensorFlow version 2.3.0 has a vulnerability in two functions, `SparseCountSparseOutput` and `RaggedCountSparseOutput`, that don't check whether the weights tensor (a data structure with values and their positions) matches the shape of the main data being processed. This missing validation allows an attacker to read data outside the intended memory area by providing fewer weights than data values, potentially exposing sensitive information from the computer's memory.
