{"id":"BIT-tensorflow-2021-29611","summary":"Incomplete validation in `SparseReshape`","details":"TensorFlow is an end-to-end open source platform for machine learning. Incomplete validation in `SparseReshape` results in a denial of service based on a `CHECK`-failure. The implementation(https://github.com/tensorflow/tensorflow/blob/e87b51ce05c3eb172065a6ea5f48415854223285/tensorflow/core/kernels/sparse_reshape_op.cc#L40) has no validation that the input arguments specify a valid sparse tensor. The fix will be included in TensorFlow 2.5.0. We will also cherrypick this commit on TensorFlow 2.4.2 and TensorFlow 2.3.3, as these are the only affected versions.","aliases":["CVE-2021-29611","GHSA-9rpc-5v9q-5r7f","PYSEC-2021-248","PYSEC-2021-539","PYSEC-2021-737"],"modified":"2025-05-20T10:02:07.006Z","published":"2024-03-06T11:18:05.657Z","database_specific":{"cpes":["cpe:2.3:a:google:tensorflow:*:*:*:*:*:*:*:*"],"severity":"Medium"},"references":[{"type":"WEB","url":"https://github.com/tensorflow/tensorflow/commit/1d04d7d93f4ed3854abf75d6b712d72c3f70d6b6"},{"type":"WEB","url":"https://github.com/tensorflow/tensorflow/security/advisories/GHSA-9rpc-5v9q-5r7f"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2021-29611"}],"affected":[{"package":{"name":"tensorflow","ecosystem":"Bitnami","purl":"pkg:bitnami/tensorflow"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2.1.4"},{"introduced":"2.2.0"},{"fixed":"2.2.3"},{"introduced":"2.3.0"},{"fixed":"2.3.3"},{"introduced":"2.4.0"},{"fixed":"2.4.2"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/tensorflow/BIT-tensorflow-2021-29611.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}],"schema_version":"1.7.3"}
