Reference binding to nullptr and heap OOB in binary cwise ops
Impact
An attacker can cause undefined behavior via binding a reference to null pointer in all binary cwise operations that don't require broadcasting (e.g., gradients of binary cwise operations):
import tensorflow as tf
tf.raw_ops.SqrtGrad(y=[4, 16],dy=[])The implementation assumes that the two inputs have exactly the same number of elements but does not check that. Hence, when the eigen functor executes it triggers heap OOB reads and undefined behavior due to binding to nullptr.
Patches
We have patched the issue in GitHub commit 93f428fd1768df147171ed674fee1fc5ab8309ec.
The fix will be included in TensorFlow 2.6.0. We will also cherrypick this commit on TensorFlow 2.5.1, TensorFlow 2.4.3, and TensorFlow 2.3.4, as these are also affected and still in supported range.
