id: PYSEC-2021-686 details: TensorFlow is an end-to-end open source platform for machine learning. An attacker can cause a heap buffer overflow in `tf.raw_ops.RaggedTensorToTensor`. This is because the implementation(https://github.com/tensorflow/tensorflow/blob/d94227d43aa125ad8b54115c03cece54f6a1977b/tensorflow/core/kernels/ragged_tensor_to_tensor_op.cc#L219-L222) uses the same index to access two arrays in parallel. Since the user controls the shape of the input arguments, an attacker could trigger a heap OOB access when `parent_output_index` is shorter than `row_split`. 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. affected: - package: name: tensorflow-gpu ecosystem: PyPI purl: pkg:pypi/tensorflow-gpu ranges: - type: GIT repo: https://github.com/tensorflow/tensorflow events: - introduced: "0" - fixed: a84358aa12f0b1518e606095ab9cfddbf597c121 - type: ECOSYSTEM events: - introduced: "0" - fixed: 2.2.0rc0 - introduced: 2.2.0 - fixed: 2.3.0rc0 - introduced: 2.3.0 - fixed: 2.3.4 - introduced: 2.4.0 - fixed: 2.4.3 versions: - 0.12.0 - 0.12.1 - 1.0.0 - 1.0.1 - 1.1.0 - 1.10.0 - 1.10.1 - 1.11.0 - 1.12.0 - 1.12.2 - 1.12.3 - 1.13.1 - 1.13.2 - 1.14.0 - 1.15.0 - 1.15.2 - 1.15.3 - 1.15.4 - 1.15.5 - 1.2.0 - 1.2.1 - 1.3.0 - 1.4.0 - 1.4.1 - 1.5.0 - 1.5.1 - 1.6.0 - 1.7.0 - 1.7.1 - 1.8.0 - 1.9.0 - 2.0.0 - 2.0.1 - 2.0.2 - 2.0.3 - 2.0.4 - 2.1.0 - 2.1.1 - 2.1.2 - 2.1.3 - 2.1.4 - 2.2.0 - 2.2.1 - 2.2.2 - 2.2.3 - 2.3.0 - 2.3.1 - 2.3.2 - 2.3.3 - 2.4.0 - 2.4.1 - 2.4.2 references: - type: ADVISORY url: https://github.com/tensorflow/tensorflow/security/advisories/GHSA-8gv3-57p6-g35r - type: FIX url: https://github.com/tensorflow/tensorflow/commit/a84358aa12f0b1518e606095ab9cfddbf597c121 aliases: - CVE-2021-29560 - GHSA-8gv3-57p6-g35r modified: "2021-12-09T06:35:25.121902Z" published: "2021-05-14T20:15:00Z"
