Impact The implementation of AddManySparseToTensorsMap is vulnerable to an integer overflow which results in a CHECK-fail when building new TensorShape objects so, an assert failure based denial of service: python import tensorflow as tf import numpy as np tf.rawops.AddManySparseToTensorsMap...

GHSA-WCV5-VRVR-3RX2 Integer Overflow or Wraparound in TensorFlow

Impact The Grappler component of TensorFlow is vulnerable to a denial of service via CHECK-failure assertion failure in constant folding: cc for const auto& outputprop : outputprops const PartialTensorShape outputshapeoutputprop.shape; // ... The outputprop tensor has a shape that is controlled b...

GHSA-J3MJ-FHPQ-QQJJ Reachable Assertion in Tensorflow

Impact When decoding a tensor from protobuf, a TensorFlow process can encounter cases where a CHECK assertion is invalidated based on user controlled arguments, if the tensors have an invalid dtype and 0 elements or an invalid shape. This allows attackers to cause denial of services in TensorFlow...

Google Tensorflow code issue vulnerability (CNVD-2022-09885)

Google TensorFlow is an end-to-end open source platform for machine learning from Google USA. Google TensorFlow is vulnerable to a code issue that stems from the fact that TensorFlow may fail to specialize types during shape inference. No detailed vulnerability details are currently available...

Denial Of Service (DoS)

Tensorflow is vulnerable to denial of service. The vulnerability exists due to a lack of santization of the CHECK assertion in shapeinference.cc file allowing an attacker to crash the system by injecting invalid dtype, 0 elements or an invalid shape...
