{"id":"GHSA-7cqx-92hp-x6wh","summary":"Heap buffer overflow in `MaxPool3DGradGrad`","details":"### Impact\nThe implementation of `tf.raw_ops.MaxPool3DGradGrad` is vulnerable to a heap buffer overflow: \n\n```python\nimport tensorflow as tf\n\nvalues = [0.01] * 11\norig_input = tf.constant(values, shape=[11, 1, 1, 1, 1], dtype=tf.float32)\norig_output = tf.constant([0.01], shape=[1, 1, 1, 1, 1], dtype=tf.float32)\ngrad = tf.constant([0.01], shape=[1, 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.MaxPool3DGradGrad(\n    orig_input=orig_input, orig_output=orig_output, grad=grad, ksize=ksize,\n    strides=strides, padding=padding)\n```\n\nThe [implementation](https://github.com/tensorflow/tensorflow/blob/596c05a159b6fbb9e39ca10b3f7753b7244fa1e9/tensorflow/core/kernels/pooling_ops_3d.cc#L694-L696) does not check that the initialization of `Pool3dParameters` completes successfully:\n\n```cc\nPool3dParameters params{context,  ksize_,       stride_,\n                        padding_, data_format_, tensor_in.shape()};\n```\n\nSince [the constructor](https://github.com/tensorflow/tensorflow/blob/596c05a159b6fbb9e39ca10b3f7753b7244fa1e9/tensorflow/core/kernels/pooling_ops_3d.cc#L48-L88) uses `OP_REQUIRES` to validate conditions, the first assertion that fails interrupts the initialization of `params`, making it contain invalid data. In turn, this might cause a heap buffer overflow, depending on default initialized values.\n\n### Patches\nWe have patched the issue in GitHub commit [63c6a29d0f2d692b247f7bf81f8732d6442fad09](https://github.com/tensorflow/tensorflow/commit/63c6a29d0f2d692b247f7bf81f8732d6442fad09).\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
