Division by zero in TFLite's convolution code ### Impact TFLite's convolution code https://github.com/tensorflow/tensorflow/blob/09c73bca7d648e961dd05898292d91a8322a9d45/tensorflow/lite/kernels/conv.cc has multiple division where the divisor is controlled by the user and not checked to be non-zero. For example: ```cc const int input_size = NumElements(input) / SizeOfDimension(input, 0); ``` ### Patches We have patched the issue in GitHub commit ff489d95a9006be080ad14feb378f2b4dac35552 https://github.com/tensorflow/tensorflow/commit/ff489d95a9006be080ad14feb378f2b4dac35552. The fix will be included in TensorFlow 2.5.0. We will also cherrypick this commit on TensorFlow 2.4.2, TensorFlow 2.3.3, TensorFlow 2.2.3 and TensorFlow 2.1.4, as these are also affected and still in supported range. ### For more information Please consult our security guide https://github.com/tensorflow/tensorflow/blob/master/SECURITY.md for more information regarding the security model and how to contact us with issues and questions. ### Attribution This vulnerability has been reported by members of the Aivul Team from Qihoo 360.
