Google TensorFlow AvgPoolOp Denial of Service Vulnerability

Google TensorFlow is an end-to-end open source platform for machine learning from Google, Inc. A denial-of-service vulnerability exists in Google TensorFlow, which stems from the AvgPoolOp function accepting a parameter ksize , which must be positive but is not checked. An attacker could exploit the vulnerability to trigger a denial-of-service attack with a negative ksize.
