{"id":"CVE-2020-15266","aliases":["BIT-tensorflow-2020-15266","GHSA-xwhf-g6j5-j5gc","PYSEC-2020-139","PYSEC-2020-296","PYSEC-2020-331"],"url":"https://o3.security/vulnerability/CVE-2020-15266","summary":"Float cast overflow undefined behavior","details":"### Impact\nWhen the `boxes` argument of `tf.image.crop_and_resize` has a very large value, the CPU kernel implementation receives it as a C++ `nan` floating point value. Attempting to operate on this is undefined behavior which later produces a segmentation fault.\n\n### Patches\n\nWe have patched the issue in c0319231333f0f16e1cc75ec83660b01fedd4182 and will release TensorFlow 2.4.0 containing the patch. TensorFlow nightly packages after this commit will also have the issue resolved.\n\n### For more information\nPlease consult [our security guide](https://github.com/tensorflow/tensorflow/blob/master/SECURITY.md) for more information regarding the security model and how to contact us with issues and questions.\n\n### Attribution\nThis vulnerability has been reported in #42129","published":"2020-10-21T21:15:12.350Z","modified":"2026-08-07T15:11:52.091517Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"PyPI","name":"tensorflow","fixedVersion":"2.4.0"},{"ecosystem":"PyPI","name":"tensorflow-cpu","fixedVersion":"2.4.0"},{"ecosystem":"PyPI","name":"tensorflow-gpu","fixedVersion":"2.4.0"}],"fix":{"url":"https://github.com/tensorflow/tensorflow/pull/42143/commits/3ade2efec2e90c6237de32a19680caaa3ebc2845","label":"tensorflow/tensorflow#42143"},"references":[{"type":"FIX","url":"https://github.com/tensorflow/tensorflow/issues/42129"},{"type":"FIX","url":"https://github.com/tensorflow/tensorflow/pull/42143/commits/3ade2efec2e90c6237de32a19680caaa3ebc2845"},{"type":"FIX","url":"https://github.com/tensorflow/tensorflow/security/advisories/GHSA-xwhf-g6j5-j5gc"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-15266"},{"type":"WEB","url":"https://github.com/pypa/advisory-database/tree/main/vulns/tensorflow-cpu/PYSEC-2020-296.yaml"},{"type":"WEB","url":"https://github.com/pypa/advisory-database/tree/main/vulns/tensorflow-gpu/PYSEC-2020-331.yaml"},{"type":"WEB","url":"https://github.com/pypa/advisory-database/tree/main/vulns/tensorflow/PYSEC-2020-139.yaml"},{"type":"PACKAGE","url":"https://github.com/tensorflow/tensorflow"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T15:11:52.091517Z"}}
