Name of the Vulnerable Software and Affected Versions TensorFlow versions prior to 1.15.5 TensorFlow versions prior to 2.0.4 TensorFlow versions prior to 2.1.3 TensorFlow versions prior to 2.2.2 TensorFlow versions prior to 2.3.2 TensorFlow versions prior to 2.4.0

Description In affected versions of TensorFlow, under certain cases, a saved model can trigger the use of uninitialized values during code execution. This issue is caused by having tensor buffers filled with the default value of the type but forgetting to default initialize the quantized floating point types in Eigen.

Recommendations For versions prior to 1.15.5, update to version 1.15.5 or later. For versions prior to 2.0.4, update to version 2.0.4 or later. For versions prior to 2.1.3, update to version 2.1.3 or later. For versions prior to 2.2.2, update to version 2.2.2 or later. For versions prior to 2.3.2, update to version 2.3.2 or later. For versions prior to 2.4.0, update to version 2.4.0 or later.
