Heap OOB write in TFLite
Impact
A specially crafted TFLite model could trigger an OOB write on heap in the TFLite implementation of ArgMin
/ArgMax
:
TfLiteIntArray* output_dims = TfLiteIntArrayCreate(NumDimensions(input) - 1);
int j = 0;
for (int i = 0; i < NumDimensions(input); ++i) {
if (i != axis_value) {
output_dims->data[j] = SizeOfDimension(input, i);
++j;
}
}
If axis_value
is not a value between 0 and NumDimensions(input)
, then the condition in the if
is never true, so code writes past the last valid element of output_dims->data
.
Patches
We have patched the issue in GitHub commit c59c37e7b2d563967da813fa50fe20b21f4da683.
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.
