Impact
The reference implementation of the
GatherNdTFLite operator is vulnerable to a division by zero error:An attacker can craft a model such that
paramsinput would be an empty tensor. In turn,params_shape.Dims(.)would be zero, in at least one dimension.Patches
We have patched the issue in GitHub commit 8e45822aa0b9f5df4b4c64f221e64dc930a70a9d.
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.
