Name of the Vulnerable Software and Affected Versions TensorFlow versions prior to 2.5.0 TensorFlow versions 2.4.2 and earlier TensorFlow versions 2.3.3 and earlier TensorFlow versions 2.2.3 and earlier TensorFlow versions 2.1.4 and earlier

Description An attacker can cause a runtime division by zero error and denial of service in tf.raw ops.QuantizedBatchNormWithGlobalNormalization. This is because the implementation does not validate all constraints specified in the op's contract.

Recommendations For versions prior to 2.5.0, update to TensorFlow 2.5.0 or later. For versions 2.4.2 and earlier, update to TensorFlow 2.4.2 or later. For versions 2.3.3 and earlier, update to TensorFlow 2.3.3 or later. For versions 2.2.3 and earlier, update to TensorFlow 2.2.3 or later. For versions 2.1.4 and earlier, update to TensorFlow 2.1.4 or later. As a temporary workaround, consider disabling the tf.raw ops.QuantizedBatchNormWithGlobalNormalization function until a patch is available.
