{"id":"CVE-2021-29613","details":"TensorFlow is an end-to-end open source platform for machine learning. Incomplete validation in `tf.raw_ops.CTCLoss` allows an attacker to trigger an OOB read from heap. The fix will be included in TensorFlow 2.5.0. We will also cherrypick these commits 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-2021-29613","GHSA-vvg4-vgrv-xfr7","PYSEC-2021-250","PYSEC-2021-541","PYSEC-2021-739"],"modified":"2026-10-20T14:11:01.116437527Z","published":"2021-05-14T20:15:16.037Z","database_specific":{},"references":[{"type":"FIX","url":"https://github.com/tensorflow/tensorflow/commit/14607c0707040d775e06b6817325640cb4b5864c"},{"type":"FIX","url":"https://github.com/tensorflow/tensorflow/commit/4504a081af71514bb1828048363e6540f797005b"},{"type":"FIX","url":"https://github.com/tensorflow/tensorflow/security/advisories/GHSA-vvg4-vgrv-xfr7"}],"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":"14607c0707040d775e06b6817325640cb4b5864c"},{"fixed":"4504a081af71514bb1828048363e6540f797005b"}],"database_specific":{"extracted_events":[{"cpe":"cpe:2.3:a:google:tensorflow:*:*:*:*:*:*:*:*","range":[{"introduced":"0"},{"fixed":"2.1.4"}],"source":"CPE_RANGE"},{"source":"CPE_RANGE","cpe":"cpe:2.3:a:google:tensorflow:*:*:*:*:*:*:*:*","range":[{"introduced":"2.2.0"},{"fixed":"2.2.3"}]},{"source":"CPE_RANGE","cpe":"cpe:2.3:a:google:tensorflow:*:*:*:*:*:*:*:*","range":[{"introduced":"2.3.0"},{"fixed":"2.3.3"}]},{"source":"CPE_RANGE","cpe":"cpe:2.3:a:google:tensorflow:*:*:*:*:*:*:*:*","range":[{"introduced":"2.4.0"},{"fixed":"2.4.2"}]},{"source":"REFERENCES_COMMIT","range":[{"fixed":"14607c0707040d775e06b6817325640cb4b5864c"}]},{"range":[{"fixed":"4504a081af71514bb1828048363e6540f797005b"}],"source":"REFERENCES_COMMIT"}]}}],"versions":["v2.1.3","v2.2.2","v2.3.2","v2.4.1","v2.1.2","v2.2.1","v2.4.0","v2.3.1","v2.2.0","v2.1.1","v2.3.0","v2.1.0","v2.1.0-rc0","v2.1.0-rc2","v2.1.0-rc1","v1.12.1","v1.9.0-rc2","v1.6.0-rc1","v1.1.0-rc2","v1.1.0-rc1","0.6.0","0.5.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2021-29613.json","vanir_signatures":[{"target":{"file":"tensorflow/core/kernels/ctc_loss_op.cc"},"deprecated":false,"digest":{"line_hashes":["164797445543339559317597264422294383972","298124281289969268493261492793776644575","284608518026634770818381073552385931273","311454208478671885915878363572511228646"],"threshold":0.9},"id":"CVE-2021-29613-6f220e82","signature_type":"Line","signature_version":"v1","source":"https://github.com/tensorflow/tensorflow/commit/14607c0707040d775e06b6817325640cb4b5864c"}],"vanir_signatures_modified":"2026-10-20T14:11:01Z"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H"}]}
