FPE in TFLite division operations
Impact
The implementation of division in TFLite is vulnerable to a division by 0 error
There is no check that the divisor tensor does not contain zero elements.
Patches
We have patched the issue in GitHub commit 1e206baedf8bef0334cca3eb92bab134ef525a28.
The fix will be included in TensorFlow 2.6.0. We will also cherrypick this commit on TensorFlow 2.5.1, TensorFlow 2.4.3, and TensorFlow 2.3.4, as these are also affected and still in supported range.
