{"id":"PYSEC-2022-157","details":"Tensorflow is an Open Source Machine Learning Framework. The `simplifyBroadcast` function in the MLIR-TFRT infrastructure in TensorFlow is vulnerable to a segfault (hence, denial of service), if called with scalar shapes. If all shapes are scalar, then `maxRank` is 0, so we build an empty `SmallVector`. The fix will be included in TensorFlow 2.8.0. This is the only affected version.","aliases":["BIT-tensorflow-2022-23593","CVE-2022-23593","GHSA-gwcx-jrx4-92w2","PYSEC-2022-102"],"modified":"2025-10-09T08:42:25.698574Z","published":"2022-02-04T23:15:00Z","references":[{"type":"WEB","url":"https://github.com/tensorflow/tensorflow/blob/274df9b02330b790aa8de1cee164b70f72b9b244/tensorflow/compiler/mlir/tfrt/jit/transforms/tf_cpurt_symbolic_shape_optimization.cc#L149-L205"},{"type":"ADVISORY","url":"https://github.com/tensorflow/tensorflow/security/advisories/GHSA-gwcx-jrx4-92w2"},{"type":"FIX","url":"https://github.com/tensorflow/tensorflow/commit/35f0fabb4c178253a964d7aabdbb15c6a398b69a"}],"affected":[{"package":{"name":"tensorflow-gpu","ecosystem":"PyPI","purl":"pkg:pypi/tensorflow-gpu"},"ranges":[{"type":"GIT","repo":"https://github.com/tensorflow/tensorflow","events":[{"introduced":"0"},{"fixed":"35f0fabb4c178253a964d7aabdbb15c6a398b69a"}]},{"type":"ECOSYSTEM","events":[{"introduced":"2.7.0"},{"fixed":"2.8.0"}]}],"versions":["2.7.0","2.7.1","2.8.0rc0","2.8.0rc1","2.7.2","2.7.3","2.7.4"],"database_specific":{"source":"https://github.com/pypa/advisory-database/blob/main/vulns/tensorflow-gpu/PYSEC-2022-157.yaml"}}],"schema_version":"1.7.3"}
