Summary

TensorFlow's Conv2D operation produces an all-zeros output when given an empty input, provided the filter and padding sizes are valid. The resulting division-by-zero floating point exceptions can be used to trigger a denial of service attack.

Mitigation

Patched in GitHub commit 611d80db29dd7b0cfb755772c69d60ae5bca05f9. The fix will be included in TensorFlow 2.10.0 and cherry-picked to TensorFlow 2.9.1, 2.8.1 and 2.7.2. No known workarounds.
