Improper Input Validation
TensorFlow is an open source platform for machine learning. Versions prior to 2.6.4, 2.7.x prior to 2.7.2, 2.8.x prior to 2.8.1 and 2.9.x prior to 2.9.0rc2, the implementation of `tf.raw_ops.StagePeek` does not fully validate the input arguments. This results in a `CHECK`-failure which can be used to trigger a denial of service attack. The code assumes `index` is a scalar but there is no validation for this before accessing its value. Versions 2.9.0rc2, 2.8.1, 2.7.2, and 2.6.4 contain a patch for this issue.
CWE-20 - Improper Input Validation
The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
