CVE-2022-23576: Integer overflow in Tensorflow
Impact The implementation of OpLevelCostEstimator::CalculateOutputSize is vulnerable to an integer overflow if an attacker can create an operation which would involve tensors with large enough number of elements: cc for (const auto& dim : outputshape.dim()) { outputsize = dim.size(); } Here, we can have a large enough number of dimensions in outputshape.dim() or just a small number of dimensions being large enough to cause an overflow in the multiplication.
Patches We have patched the issue in GitHub commit b9bd6cfd1c50e6807846af9a86f9b83cafc9c8ae.
The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3, as these are also affected and still in supported range.
