{"id":"BIT-tensorflow-2020-15194","summary":"Denial of Service in Tensorflow","details":"In Tensorflow before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, the `SparseFillEmptyRowsGrad` implementation has incomplete validation of the shapes of its arguments. Although `reverse_index_map_t` and `grad_values_t` are accessed in a similar pattern, only `reverse_index_map_t` is validated to be of proper shape. Hence, malicious users can pass a bad `grad_values_t` to trigger an assertion failure in `vec`, causing denial of service in serving installations. 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-2020-15194","GHSA-9mqp-7v2h-2382","PYSEC-2020-117","PYSEC-2020-274","PYSEC-2020-309"],"modified":"2025-05-20T10:02:07.006Z","published":"2024-03-06T11:20:47.450Z","database_specific":{"severity":"Medium","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-9mqp-7v2h-2382"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-15194"}],"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-2020-15194.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L"}]}],"schema_version":"1.7.3"}
