Division by zero in TFLite's implementation of `SVDF` ### Impact The implementation of the `SVDF` TFLite operator is vulnerable to a division by zero error https://github.com/tensorflow/tensorflow/blob/7f283ff806b2031f407db64c4d3edcda8fb9f9f5/tensorflow/lite/kernels/svdf.cc#L99-L102: ```cc const int rank = params->rank; ... TF_LITE_ENSURE_EQ(context, num_filters % rank, 0); ``` An attacker can craft a model such that `params->rank` would be 0. ### Patches We have patched the issue in GitHub commit 6841e522a3e7d48706a02e8819836e809f738682 https://github.com/tensorflow/tensorflow/commit/6841e522a3e7d48706a02e8819836e809f738682. 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.
