GHSA-26J7-6W8W-7922

Vulnerability from github – Published: 2021-05-21 14:26 – Updated: 2024-11-13 16:01

Summary
Division by zero in optimized pooling implementations in TFLite
Details

Impact

Optimized pooling implementations in TFLite fail to check that the stride arguments are not 0 before calling ComputePaddingHeightWidth.

Since users can craft special models which will have params->stride_{height,width} be zero, this will result in a division by zero.

Patches

We have patched the issue in GitHub commit 5f7975d09eac0f10ed8a17dbb6f5964977725adc.

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.
