Description

Stack overflow in ParseAttrValue with nested tensors (CVE-2021-29615)

Details

TensorFlow is an end-to-end open source platform for machine learning. The implementation of ParseAttrValue(https://github.com/tensorflow/tensorflow/blob/c22d88d6ff33031aa113e48aa3fc9aa74ed79595/tensorflow/core/framework/attr_value_util.cc#L397-L453) can be tricked into stack overflow due to recursion by giving in a specially crafted input. The fix will be included in TensorFlow 2.5.0. We will also cherrypick this commit on TensorFlow 2.4.2, TensorFlow 2.3.3, TensorFlow 2.2.3 and TensorFlow 2.1.4, as these are also affected and still in supported range.

Reason for inclusion in AVID: This CVE affects TensorFlow, a core AI framework used in building and running AI models and pipelines. It describes a vulnerability in a software component (ParseAttrValue) of the AI software stack that can be triggered by crafted input, leading to a stack overflow (uncontrolled recursion). The issue impacts multiple TensorFlow versions and has a documented fix in newer releases, indicating a genuine security vulnerability in a software supply chain component used for general-purpose AI systems (training, serving, tooling). The report provides enough signal: vulnerability type, affected versions, and remediation. Therefore, it should be kept for AVID curation as a vulnerability in the AI software supply chain.
