{"id":"BIT-tensorflow-2020-15196","summary":"Heap buffer overflow in Tensorflow","details":"In Tensorflow version 2.3.0, the `SparseCountSparseOutput` and `RaggedCountSparseOutput` implementations don't validate that the `weights` tensor has the same shape as the data. The check exists for `DenseCountSparseOutput`, where both tensors are fully specified. In the sparse and ragged count weights are still accessed in parallel with the data. But, since there is no validation, a user passing fewer weights than the values for the tensors can generate a read from outside the bounds of the heap buffer allocated for the weights. The issue is patched in commit 3cbb917b4714766030b28eba9fb41bb97ce9ee02 and is released in TensorFlow version 2.3.1.","aliases":["CVE-2020-15196","GHSA-pg59-2f92-5cph","PYSEC-2020-119","PYSEC-2020-276","PYSEC-2020-311"],"modified":"2025-05-20T10:02:07.006Z","published":"2024-03-06T11:20:44.959Z","database_specific":{"severity":"Critical","cpes":["cpe:2.3:a:google:tensorflow:2.3.0:*:*:*:-:*:*:*","cpe:2.3:a:google:tensorflow:*:*:*:*:-:*:*:*"]},"references":[{"type":"WEB","url":"https://github.com/tensorflow/tensorflow/commit/3cbb917b4714766030b28eba9fb41bb97ce9ee02"},{"type":"WEB","url":"https://github.com/tensorflow/tensorflow/releases/tag/v2.3.1"},{"type":"WEB","url":"https://github.com/tensorflow/tensorflow/security/advisories/GHSA-pg59-2f92-5cph"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-15196"}],"affected":[{"package":{"name":"tensorflow","ecosystem":"Bitnami","purl":"pkg:bitnami/tensorflow"},"ranges":[{"type":"SEMVER","events":[{"introduced":"2.3.0"},{"fixed":"2.3.1"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/tensorflow/BIT-tensorflow-2020-15196.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"}]}],"schema_version":"1.7.3"}
