{"id":"BIT-tensorflow-2020-15195","summary":"Heap buffer overflow in Tensorflow","details":"In Tensorflow before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, the implementation of `SparseFillEmptyRowsGrad` uses a double indexing pattern. It is possible for `reverse_index_map(i)` to be an index outside of bounds of `grad_values`, thus resulting in a heap buffer overflow. The issue is patched in commit 390611e0d45c5793c7066110af37c8514e6a6c54, and is released in TensorFlow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1, or 2.3.1.","aliases":["CVE-2020-15195","GHSA-63xm-rx5p-xvqr","PYSEC-2020-118","PYSEC-2020-275","PYSEC-2020-310"],"modified":"2025-05-20T10:02:07.006Z","published":"2024-03-06T11:20:46.206Z","database_specific":{"severity":"High","cpes":["cpe:2.3:a:google:tensorflow:*:*:*:*:-:*:*:*"]},"references":[{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00065.html"},{"type":"WEB","url":"https://github.com/tensorflow/tensorflow/commit/390611e0d45c5793c7066110af37c8514e6a6c54"},{"type":"WEB","url":"https://github.com/tensorflow/tensorflow/releases/tag/v2.3.1"},{"type":"WEB","url":"https://github.com/tensorflow/tensorflow/security/advisories/GHSA-63xm-rx5p-xvqr"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-15195"}],"affected":[{"package":{"name":"tensorflow","ecosystem":"Bitnami","purl":"pkg:bitnami/tensorflow"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.15.4"},{"introduced":"2.0.0"},{"fixed":"2.0.3"},{"introduced":"2.1.0"},{"fixed":"2.1.2"},{"introduced":"2.2.0"},{"fixed":"2.2.1"},{"introduced":"2.3.0"},{"fixed":"2.3.1"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/tensorflow/BIT-tensorflow-2020-15195.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}],"schema_version":"1.7.3"}
