Details

TensorFlow is an end-to-end open source platform for machine learning. In affected versions the implementation of sparse reduction operations in TensorFlow can trigger accesses outside of bounds of heap allocated data. The implementation fails to validate that each reduction group does not overflow and that each corresponding index does not point to outside the bounds of the input tensor. We have patched the issue in GitHub commit 87158f43f05f2720a374f3e6d22a7aaa3a33f750. The fix will be included in TensorFlow 2.6.0. We will also cherrypick this commit on TensorFlow 2.5.1, TensorFlow 2.4.3, and TensorFlow 2.3.4, as these are also affected and still in supported range.

Vulnerability from github

Severity ?

7.3 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:H

Summary

Heap out of bounds access in sparse reduction operations

Details

Impact

The implementation of sparse reduction operations in TensorFlow can trigger accesses outside of bounds of heap allocated data:

```python import tensorflow as tf

x = tf.SparseTensor( indices=[[773, 773, 773], [773, 773, 773]], values=[1, 1], dense_shape=[337, 337, 337]) tf.sparse.reduce_sum(x, 1) ```

The implementation fails to validate that each reduction group does not overflow and that each corresponding index does not point to outside the bounds of the input tensor.

Patches

We have patched the issue in GitHub commit 87158f43f05f2720a374f3e6d22a7aaa3a33f750.

The fix will be included in TensorFlow 2.6.0. We will also cherrypick this commit on TensorFlow 2.5.1, TensorFlow 2.4.3, and TensorFlow 2.3.4, as these are also affected and still in supported range.

  "details": "### Impact\nThe implementation of sparse reduction operations in TensorFlow can trigger accesses outside of bounds of heap allocated data:\n\n```python\nimport tensorflow as tf\n\nx = tf.SparseTensor(\n      indices=[[773, 773, 773], [773, 773, 773]],\n      values=[1, 1],\n      dense_shape=[337, 337, 337])\ntf.sparse.reduce_sum(x, 1)\n```\n\nThe [implementation](https://github.com/tensorflow/tensorflow/blob/a1bc56203f21a5a4995311825ffaba7a670d7747/tensorflow/core/kernels/sparse_reduce_op.cc#L217-L228) fails to validate that each reduction group does not overflow and that each corresponding index does not point to outside the bounds of the input tensor.\n\n### Patches\nWe have patched the issue in GitHub commit [87158f43f05f2720a374f3e6d22a7aaa3a33f750](https://github.com/tensorflow/tensorflow/commit/87158f43f05f2720a374f3e6d22a7aaa3a33f750). \n\nThe fix will be included in TensorFlow 2.6.0. We will also cherrypick this commit on TensorFlow 2.5.1, TensorFlow 2.4.3, and TensorFlow 2.3.4, as these are also affected and still in supported range.\n\n### For more information\nPlease consult [our security guide](https://github.com/tensorflow/tensorflow/blob/master/SECURITY.md) for more information regarding the security model and how to contact us with issues and questions.\n\n### Attribution\nThis vulnerability has been reported by members of the Aivul Team from Qihoo 360.",
