{"id":"BIT-tensorflow-2020-15201","summary":"Heap buffer overflow in Tensorflow","details":"In Tensorflow before version 2.3.1, the `RaggedCountSparseOutput` implementation does not validate that the input arguments form a valid ragged tensor. In particular, there is no validation that the values in the `splits` tensor generate a valid partitioning of the `values` tensor. Hence, the code is prone to heap buffer overflow. If `split_values` does not end with a value at least `num_values` then the `while` loop condition will trigger a read outside of the bounds of `split_values` once `batch_idx` grows too large. The issue is patched in commit 3cbb917b4714766030b28eba9fb41bb97ce9ee02 and is released in TensorFlow version 2.3.1.","aliases":["CVE-2020-15201","GHSA-p5f8-gfw5-33w4","PYSEC-2020-124","PYSEC-2020-281","PYSEC-2020-316"],"modified":"2025-05-20T10:02:07.006Z","published":"2024-03-06T11:20:38.643Z","database_specific":{"severity":"Medium","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-p5f8-gfw5-33w4"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-15201"}],"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-2020-15201.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N"}]}],"schema_version":"1.7.3"}
