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 The implementation of the DepthwiseConv TFLite operator is vulnerable to a division by zero error. An attacker can craft a model such that the input's fourth dimension would be 0.

Recommendations For versions prior to 2.5.0, update to TensorFlow 2.5.0 or later to resolve the issue. For versions 2.4.2 and earlier, update to TensorFlow 2.4.2 or later to resolve the issue. For versions 2.3.3 and earlier, update to TensorFlow 2.3.3 or later to resolve the issue. For versions 2.2.3 and earlier, update to TensorFlow 2.2.3 or later to resolve the issue. For versions 2.1.4 and earlier, update to TensorFlow 2.1.4 or later to resolve the issue.
