BIT-TENSORFLOW-2022-21730 Out of bounds read in Tensorflow

Tensorflow is an Open Source Machine Learning Framework. The implementation of FractionalAvgPoolGrad does not consider cases where the input tensors are invalid allowing an attacker to read from outside of bounds of heap. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this...

BIT-TENSORFLOW-2022-23583 `CHECK`-failures in binary ops in Tensorflow

Tensorflow is an Open Source Machine Learning Framework. A malicious user can cause a denial of service by altering a SavedModel such that any binary op would trigger CHECK failures. This occurs when the protobuf part corresponding to the tensor arguments is modified such that the dtype no longer...

BIT-TENSORFLOW-2022-35938 OOB read in `Gather_nd` op in TensorFlow Lite Micro

TensorFlow is an open source platform for machine learning. The GatherNd function takes arguments that determine the sizes of inputs and outputs. If the inputs given are greater than or equal to the sizes of the outputs, an out-of-bounds memory read or a crash is triggered. This issue has been...

BIT-TENSORFLOW-2022-35952 `CHECK` failures in `UnbatchGradOp` in TensorFlow

TensorFlow is an open source platform for machine learning. The UnbatchGradOp function takes an argument id that is assumed to be a scalar. A nonscalar id can trigger a CHECK failure and crash the program. It also requires its argument batchindex to contain three times the number of elements as...

BIT-TENSORFLOW-2022-35970 Segfault in `QuantizedInstanceNorm` in TensorFlow

TensorFlow is an open source platform for machine learning. If QuantizedInstanceNorm is given xmin or xmax tensors of a nonzero rank, it results in a segfault that can be used to trigger a denial of service attack. We have patched the issue in GitHub commit 785d67a78a1d533759fcd2f5e8d6ef778de849e...

BIT-TENSORFLOW-2022-35971 `CHECK` fail in `FakeQuantWithMinMaxVars` in TensorFlow

TensorFlow is an open source platform for machine learning. If FakeQuantWithMinMaxVars is given min or max tensors of a nonzero rank, it results in a CHECK fail that can be used to trigger a denial of service attack. We have patched the issue in GitHub commit...

BIT-TENSORFLOW-2022-35982 Segfault in `SparseBincount` in TensorFlow

TensorFlow is an open source platform for machine learning. If SparseBincount is given inputs for indices, values, and denseshape that do not make a valid sparse tensor, it results in a segfault that can be used to trigger a denial of service attack. We have patched the issue in GitHub commit...

BIT-TENSORFLOW-2022-35985 `CHECK` fail in `LRNGrad` in TensorFlow

TensorFlow is an open source platform for machine learning. If LRNGrad is given an outputimage input tensor that is not 4-D, it results in a CHECK fail that can be used to trigger a denial of service attack. We have patched the issue in GitHub commit bd90b3efab4ec958b228cd7cfe9125be1c0cf255. The...

BIT-TENSORFLOW-2022-35991 `CHECK` fail in `TensorListScatter` and `TensorListScatterV2` in TensorFlow
