Details

Heap OOB in `QuantizeAndDequantizeV3` ### Impact An attacker can read data outside of bounds of heap allocated buffer in `tf.raw_ops.QuantizeAndDequantizeV3`: ```python import tensorflow as tf tf.raw_ops.QuantizeAndDequantizeV3( input=[2.5,2.5], input_min=[0,0], input_max=[1,1], num_bits=[30], signed_input=False, range_given=False, narrow_range=False, axis=3) ``` This 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: ```cc const int depth = (axis_ == -1) ? 1 : input.dim_size(axis_); ``` ### Patches We have patched the issue in GitHub commit [99085e8ff02c3763a0ec2263e44daec416f6a387](https://github.com/tensorflow/tensorflow/commit/99085e8ff02c3763a0ec2263e44daec416f6a387). The 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. ### For more information Please 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. ### Attribution This vulnerability has been reported by Aivul Team from Qihoo 360.
