{"id":"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.","aliases":["BIT-tensorflow-2021-29615","GHSA-qw5h-7f53-xrp6","PYSEC-2021-252","PYSEC-2021-543","PYSEC-2021-741"],"modified":"2026-04-11T17:25:51.443254Z","published":"2021-05-14T20:15:16.127Z","related":["GHSA-qw5h-7f53-xrp6"],"references":[{"type":"FIX","url":"https://github.com/tensorflow/tensorflow/commit/e07e1c3d26492c06f078c7e5bf2d138043e199c1"},{"type":"FIX","url":"https://github.com/tensorflow/tensorflow/security/advisories/GHSA-qw5h-7f53-xrp6"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/tensorflow/tensorflow","events":[{"introduced":"0"},{"fixed":"0931ea3d985bb9c8fdd054a5e29c4129623c849b"},{"introduced":"2b96f3662bd776e277f86997659e61046b56c315"},{"fixed":"cfe0c80169ae984bcdc99ff6de7444164aaa8e07"},{"introduced":"b36436b087bd8e8701ef51718179037cccdfc26e"},{"fixed":"3929ffacfbef7c431e8397920d040aaf47acff19"},{"introduced":"582c8d236cb079023657287c318ff26adb239002"},{"fixed":"1923123d32ea41d92b70a27a3f6ecf0763b56f6c"},{"fixed":"e07e1c3d26492c06f078c7e5bf2d138043e199c1"}],"database_specific":{"versions":[{"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"}]}}],"versions":["0.5.0","0.6.0","v1.1.0-rc1","v1.1.0-rc2","v1.12.1","v1.6.0-rc1","v1.9.0-rc2","v2.1.0","v2.1.0-rc0","v2.1.0-rc1","v2.1.0-rc2","v2.1.1","v2.1.2","v2.1.3","v2.2.0","v2.2.1","v2.2.2","v2.3.0","v2.3.1","v2.3.2","v2.4.0","v2.4.1"],"database_specific":{"vanir_signatures_modified":"2026-04-11T17:25:51Z","vanir_signatures":[{"signature_type":"Function","target":{"function":"ParseAttrValue","file":"tensorflow/core/framework/attr_value_util.cc"},"id":"CVE-2021-29615-5bef843d","digest":{"length":1480,"function_hash":"161123823544461413250116767507509085187"},"deprecated":false,"signature_version":"v1","source":"https://github.com/tensorflow/tensorflow/commit/e07e1c3d26492c06f078c7e5bf2d138043e199c1"},{"signature_type":"Line","target":{"file":"tensorflow/core/framework/attr_value_util.cc"},"id":"CVE-2021-29615-6d26c6ff","digest":{"line_hashes":["130491718664554948992035178782741890805","307524391018127699555412904581496237494","206176602397166642415421419916276165628","132752298504289257637866894390435825312","18628081833363303415322345815175110902","14164033325410267613033608022580933608","119251591795085005131396724163308884511","19118296530534102096758683814182968170","73338673258351910983383266073684882720"],"threshold":0.9},"deprecated":false,"signature_version":"v1","source":"https://github.com/tensorflow/tensorflow/commit/e07e1c3d26492c06f078c7e5bf2d138043e199c1"}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2021-29615.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
