Impact
An attacker can cause a heap buffer overflow in
tf.raw_ops.SparseSplit
:This is because the implementation accesses an array element based on a user controlled offset:
This results in overriding values on the heap.
Patches
We have patched the issue in GitHub commit 8ba6fa29cd8bf9cef9b718dc31c78c73081f5b31.
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.
