Improper Check for Unusual or Exceptional Conditions


Severity Medium
Score 5.5/10


TensorFlow is an end-to-end open source platform for machine learning. On versions before 2.1.4, 2.2.0 through 2.2.2, 2.3.0 through 2.3.2 and 2.4.0 through 2.4.1, an attacker can trigger a denial of service via a `CHECK`-fail in `tf.raw_ops.SparseConcat`. This is because the implementation( takes the values specified in `shapes[0]` as dimensions for the output shape. The `TensorShape` constructor( uses a `CHECK` operation which triggers when `InitDims`( returns a non-OK status. This is a legacy implementation of the constructor and operations should use `BuildTensorShapeBase` or `AddDimWithStatus` to prevent `CHECK`-failures in the presence of overflows.
