Division by zero in TFLite's implementation of Split
The implementation of the
Split TFLite operator is vulnerable to a division by zero error:
TF_LITE_ENSURE_MSG(context, input_size % num_splits == 0, "Not an even split"); const int slice_size = input_size / num_splits;
An attacker can craft a model such that
num_splits would be 0.
We have patched the issue in GitHub commit b22786e7e9b7bdb6a56936ff29cc7e9968d7bc1d.
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.
