An attacker can cause a denial of service by…","summary":"TensorFlow's UnsortedSegmentJoin operator assumes its num_segments tensor argument is a valid scalar. An attacker who controls that argument can pass an empty tensor, which invalidates a CHECK in .scalar<T>()() and terminates the process, causing a denial of service.","solution":"The fix will be included in TensorFlow 2.5.0.
