Summary
Division by zero in TFLite's implementation of `TransposeConv`
Details

Impact

The optimized implementation of the TransposeConv TFLite operator is vulnerable to a division by zero error:

int height_col = (height + pad_t + pad_b - filter_h) / stride_h + 1;
int width_col = (width + pad_l + pad_r - filter_w) / stride_w + 1;

An attacker can craft a model such that stride_{h,w} values are 0. Code calling this function must validate these arguments.

Patches

We have patched the issue in GitHub commit 801c1c6be5324219689c98e1bd3e0ca365ee834d.

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.
