GHSA-ffjm-4qwc-7cmf: TensorFlow vulnerable to OOB write in `scatter_nd` in TF Lite
Impact
The ScatterNd function takes an input argument that determines the indices of of the output tensor. An input index greater than the output tensor or less than zero will either write content at the wrong index or trigger a crash.
Patches
We have patched the issue in GitHub commit b4d4b4cb019bd7240a52daa4ba61e3cc814f0384.
The fix will be included in TensorFlow 2.10.0. We will also cherrypick this commit on TensorFlow 2.9.1, TensorFlow 2.8.1, and TensorFlow 2.7.2, as these are also affected and still in supported range.
