Attempting to operate on this is undefined behavior which later produces a segmentation fault.\n\n### Patches\n\nWe have patched the issue in c0319231333f0f16e1cc75ec83660b01fedd4182 and will release TensorFlow 2.4.0 containing the patch. TensorFlow nightly packages after this commit will also have the issue resolved.\n\n### For more information\nPlease consult [our security guide](https://github.com/tensorflow/tensorflow/blob/master/SECURITY.md) for more information regarding the security model and how to contact us with issues and questions.\n\n### Attribution\nThis vulnerability has been reported in #42129\n\n## Affected packages\n\n- `tensorflow < 2.4.0`\n- `tensorflow-cpu < 2.4.0`\n- `tensorflow-gpu < 2.4.0`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `tensorflow 2.4.0`\n- `tensorflow-cpu 2.4.0`\n- `tensorflow-gpu 2.4.0`","depth":"sunlit","depthScore":21,"depthScoreParts":{"impact":20.4,"likelihood":0.2,"exploitation":0,"ransomware":0},"changes":[]}
