Details

Missing validation in shape inference for `Dequantize` ### Impact The shape inference code for `tf.raw_ops.Dequantize` has a vulnerability that could trigger a denial of service via a segfault if an attacker provides invalid arguments: ```python import tensorflow as tf tf.compat.v1.disable_v2_behavior() tf.raw_ops.Dequantize( input_tensor = tf.constant(-10.0, dtype=tf.float32), input_tensor = tf.cast(input_tensor, dtype=tf.quint8), min_range = tf.constant([], shape=[0], dtype=tf.float32), max_range = tf.constant([], shape=[0], dtype=tf.float32), mode = 'MIN_COMBINED', narrow_range=False, axis=-10, dtype=tf.dtypes.float32) ``` The shape inference [implementation](https://github.com/tensorflow/tensorflow/blob/460e000de3a83278fb00b61a16d161b1964f15f4/tensorflow/core/ops/array_ops.cc#L2999-L3014) uses `axis` to select between two different values for `minmax_rank` which is then used to retrieve tensor dimensions. However, code assumes that `axis` can be either `-1` or a value greater than `-1`, with no validation for the other values. ### Patches We have patched the issue in GitHub commit [da857cfa0fde8f79ad0afdbc94e88b5d4bbec764](https://github.com/tensorflow/tensorflow/commit/da857cfa0fde8f79ad0afdbc94e88b5d4bbec764). 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. ### 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 Yakun Zhang of Baidu Security.
