{"id":"BIT-tensorflow-2020-15204","summary":"Segfault in Tensorflow","details":"In eager mode, TensorFlow before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1 does not set the session state. Hence, calling `tf.raw_ops.GetSessionHandle` or `tf.raw_ops.GetSessionHandleV2` results in a null pointer dereference In linked snippet, in eager mode, `ctx-\u003esession_state()` returns `nullptr`. Since code immediately dereferences this, we get a segmentation fault. The issue is patched in commit 9a133d73ae4b4664d22bd1aa6d654fec13c52ee1, and is released in TensorFlow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1, or 2.3.1.","aliases":["CVE-2020-15204","GHSA-q8gv-q7wr-9jf8","PYSEC-2020-127","PYSEC-2020-284","PYSEC-2020-319"],"modified":"2025-05-20T10:02:07.006Z","published":"2024-03-06T11:20:34.916Z","database_specific":{"cpes":["cpe:2.3:a:google:tensorflow:*:*:*:*:-:*:*:*"],"severity":"Medium"},"references":[{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00065.html"},{"type":"WEB","url":"https://github.com/tensorflow/tensorflow/commit/9a133d73ae4b4664d22bd1aa6d654fec13c52ee1"},{"type":"WEB","url":"https://github.com/tensorflow/tensorflow/releases/tag/v2.3.1"},{"type":"WEB","url":"https://github.com/tensorflow/tensorflow/security/advisories/GHSA-q8gv-q7wr-9jf8"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-15204"}],"affected":[{"package":{"name":"tensorflow","ecosystem":"Bitnami","purl":"pkg:bitnami/tensorflow"},"ranges":[{"type":"SEMVER","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"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/tensorflow/BIT-tensorflow-2020-15204.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L"}]}],"schema_version":"1.7.3"}
