{"id":"PYSEC-2020-287","details":"In tensorflow-lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, to mimic Python's indexing with negative values, TFLite uses `ResolveAxis` to convert negative values to positive indices. However, the only check that the converted index is now valid is only present in debug builds. If the `DCHECK` does not trigger, then code execution moves ahead with a negative index. This, in turn, results in accessing data out of bounds which results in segfaults and/or data corruption. The issue is patched in commit 2d88f470dea2671b430884260f3626b1fe99830a, and is released in TensorFlow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1, or 2.3.1.","aliases":["BIT-tensorflow-2020-15207","CVE-2020-15207","GHSA-q4qf-3fc6-8x34","PYSEC-2020-130","PYSEC-2020-322"],"modified":"2023-12-06T01:00:17.062955Z","published":"2020-09-25T19:15:00Z","references":[{"type":"FIX","url":"https://github.com/tensorflow/tensorflow/commit/2d88f470dea2671b430884260f3626b1fe99830a"},{"type":"ADVISORY","url":"https://github.com/tensorflow/tensorflow/security/advisories/GHSA-q4qf-3fc6-8x34"},{"type":"WEB","url":"https://github.com/tensorflow/tensorflow/releases/tag/v2.3.1"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00065.html"}],"affected":[{"package":{"name":"tensorflow-cpu","ecosystem":"PyPI","purl":"pkg:pypi/tensorflow-cpu"},"ranges":[{"type":"GIT","repo":"https://github.com/tensorflow/tensorflow","events":[{"introduced":"0"},{"fixed":"2d88f470dea2671b430884260f3626b1fe99830a"}]},{"type":"ECOSYSTEM","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"}]}],"versions":["1.15.0","2.1.0","2.1.1","2.2.0","2.3.0"],"database_specific":{"source":"https://github.com/pypa/advisory-database/blob/main/vulns/tensorflow-cpu/PYSEC-2020-287.yaml"}}],"schema_version":"1.7.3"}
