{"id":"GHSA-h9px-9vqg-222h","summary":"Heap OOB in `QuantizeAndDequantizeV3`","details":"### Impact\nAn attacker can read data outside of bounds of heap allocated buffer in `tf.raw_ops.QuantizeAndDequantizeV3`:\n\n```python\nimport tensorflow as tf\n\ntf.raw_ops.QuantizeAndDequantizeV3(\n  input=[2.5,2.5], input_min=[0,0], input_max=[1,1], num_bits=[30],\n  signed_input=False, range_given=False, narrow_range=False, axis=3)\n```   \n\nThis is because the [implementation](https://github.com/tensorflow/tensorflow/blob/11ff7f80667e6490d7b5174aa6bf5e01886e770f/tensorflow/core/kernels/quantize_and_dequantize_op.cc#L237) does not validate the value of user supplied `axis` attribute before using it to index in the array backing the `input` argument:\n\n```cc\nconst int depth = (axis_ == -1) ? 1 : input.dim_size(axis_);\n```\n\n### Patches\nWe have patched the issue in GitHub commit [99085e8ff02c3763a0ec2263e44daec416f6a387](https://github.com/tensorflow/tensorflow/commit/99085e8ff02c3763a0ec2263e44daec416f6a387).\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
