{"id":"BIT-tensorflow-2020-26270","summary":"CHECK-fail in LSTM with zero-length input in TensorFlow","details":"In affected versions of TensorFlow running an LSTM/GRU model where the LSTM/GRU layer receives an input with zero-length results in a CHECK failure when using the CUDA backend. This can result in a query-of-death vulnerability, via denial of service, if users can control the input to the layer. This is fixed in versions 1.15.5, 2.0.4, 2.1.3, 2.2.2, 2.3.2, and 2.4.0.","aliases":["CVE-2020-26270","GHSA-m648-33qf-v3gp","PYSEC-2020-256","PYSEC-2020-301","PYSEC-2020-336"],"modified":"2025-05-20T10:02:07.006Z","published":"2024-03-06T11:20:13.620Z","database_specific":{"cpes":["cpe:2.3:a:google:tensorflow:*:*:*:*:*:*:*:*"],"severity":"Low"},"references":[{"type":"WEB","url":"https://github.com/tensorflow/tensorflow/commit/14755416e364f17fb1870882fa778c7fec7f16e3"},{"type":"WEB","url":"https://github.com/tensorflow/tensorflow/security/advisories/GHSA-m648-33qf-v3gp"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-26270"}],"affected":[{"package":{"name":"tensorflow","ecosystem":"Bitnami","purl":"pkg:bitnami/tensorflow"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.15.5"},{"introduced":"2.0.0"},{"fixed":"2.0.4"},{"introduced":"2.1.0"},{"fixed":"2.1.3"},{"introduced":"2.2.0"},{"fixed":"2.2.2"},{"introduced":"2.3.0"},{"fixed":"2.3.2"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/tensorflow/BIT-tensorflow-2020-26270.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L"}]}],"schema_version":"1.7.3"}
