Heap buffer overflow in Transpose
Impact
The shape inference function for Transpose is vulnerable to a heap buffer overflow:
This occurs whenever perm contains negative elements. The shape inference function does not validate that the indices in perm are all valid:
where Dim(tensor, index) accepts either a positive index less than the rank of the tensor or the special value -1 for unknown dimensions.
Patches
We have patched the issue in GitHub commit c79ba87153ee343401dbe9d1954d7f79e521eb14.
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.
