CVE-2021-29561: Reachable Assertion
(updated )
TensorFlow is an end-to-end open source platform for machine learning. An attacker can cause a denial of service by exploiting a CHECK
-failure coming from tf.raw_ops.LoadAndRemapMatrix
. This is because the implementation assumes that the ckpt_path
is always a valid scalar. However, an attacker can send any other tensor as the first argument of LoadAndRemapMatrix
. This would cause the rank CHECK
in scalar<T>()()
to trigger and terminate the process.
