{"cve":"CVE-2020-15213","nvd":{"published":"2020-09-25T19:15:16.603","modified":"2026-06-17T02:56:16.920","status":"Modified","description":"In TensorFlow Lite before versions 2.2.1 and 2.3.1, models using segment sum can trigger a denial of service by causing an out of memory allocation in the implementation of segment sum. Since code uses the last element of the tensor holding them to determine the dimensionality of output tensor, attackers can use a very large value to trigger a large allocation. The issue is patched in commit 204945b19e44b57906c9344c0d00120eeeae178a and is released in TensorFlow versions 2.2.1, or 2.3.1. A potential workaround would be to add a custom `Verifier` to limit the maximum value in the segment ids tensor. This only handles the case when the segment ids are stored statically in the model, but a similar validation could be done if the segment ids are generated at runtime, between inference steps. However, if the segment ids are generated as outputs of a tensor during inference steps, then there are no possible workaround and users are advised to upgrade to patched code.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:N/A:L","score":4.0},"cwes":["CWE-770","CWE-119"],"references":["https://github.com/tensorflow/tensorflow/commit/204945b19e44b57906c9344c0d00120eeeae178a","https://github.com/tensorflow/tensorflow/releases/tag/v2.3.1","https://github.com/tensorflow/tensorflow/security/advisories/GHSA-hjmq-236j-8m87","https://github.com/tensorflow/tensorflow/commit/204945b19e44b57906c9344c0d00120eeeae178a","https://github.com/tensorflow/tensorflow/releases/tag/v2.3.1"],"products":["google:tensorflow"],"source":"nvd","synced_at":"2026-10-19T21:09:53.489947993+00:00"},"epss":{"cve":"CVE-2020-15213","score":0.0076,"percentile":0.55294,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-hjmq-236j-8m87","url":"https://osv.dev/vulnerability/GHSA-hjmq-236j-8m87","summary":"Denial of service in tensorflow-lite","modified":"2026-07-08T06:28:11.675658492Z","packages":[{"ecosystem":"PyPI","name":"tensorflow","purl":"pkg:pypi/tensorflow","ranges":[">=2.2.0 <2.2.1"],"fixed":["2.2.1"]},{"ecosystem":"PyPI","name":"tensorflow","purl":"pkg:pypi/tensorflow","ranges":[">=2.3.0 <2.3.1"],"fixed":["2.3.1"]},{"ecosystem":"PyPI","name":"tensorflow-cpu","purl":"pkg:pypi/tensorflow-cpu","ranges":[">=2.2.0 <2.2.1"],"fixed":["2.2.1"]},{"ecosystem":"PyPI","name":"tensorflow-cpu","purl":"pkg:pypi/tensorflow-cpu","ranges":[">=2.3.0 <2.3.1"],"fixed":["2.3.1"]},{"ecosystem":"PyPI","name":"tensorflow-gpu","purl":"pkg:pypi/tensorflow-gpu","ranges":[">=2.2.0 <2.2.1"],"fixed":["2.2.1"]},{"ecosystem":"PyPI","name":"tensorflow-gpu","purl":"pkg:pypi/tensorflow-gpu","ranges":[">=2.3.0 <2.3.1"],"fixed":["2.3.1"]}]},{"id":"PYSEC-2020-136","url":"https://osv.dev/vulnerability/PYSEC-2020-136","summary":"","modified":"2023-12-06T01:00:17.426912Z","packages":[{"ecosystem":"PyPI","name":"tensorflow","purl":"pkg:pypi/tensorflow","ranges":[">=2.2.0 <2.2.1",">=2.3.0 <2.3.1"],"fixed":["2.2.1","2.3.1"]}]},{"id":"PYSEC-2020-293","url":"https://osv.dev/vulnerability/PYSEC-2020-293","summary":"","modified":"2023-12-06T01:00:17.426912Z","packages":[{"ecosystem":"PyPI","name":"tensorflow-cpu","purl":"pkg:pypi/tensorflow-cpu","ranges":[">=2.2.0 <2.2.1",">=2.3.0 <2.3.1"],"fixed":["2.2.1","2.3.1"]}]},{"id":"PYSEC-2020-328","url":"https://osv.dev/vulnerability/PYSEC-2020-328","summary":"","modified":"2023-12-06T01:00:17.426912Z","packages":[{"ecosystem":"PyPI","name":"tensorflow-gpu","purl":"pkg:pypi/tensorflow-gpu","ranges":[">=2.2.0 <2.2.1",">=2.3.0 <2.3.1"],"fixed":["2.2.1","2.3.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
