{"id":"PYSEC-2020-278","details":"In Tensorflow before version 2.3.1, the `SparseCountSparseOutput` implementation does not validate that the input arguments form a valid sparse tensor. In particular, there is no validation that the `indices` tensor has the same shape as the `values` one. The values in these tensors are always accessed in parallel. Thus, a shape mismatch can result in accesses outside the bounds of heap allocated buffers. The issue is patched in commit 3cbb917b4714766030b28eba9fb41bb97ce9ee02 and is released in TensorFlow version 2.3.1.","aliases":["BIT-tensorflow-2020-15198","CVE-2020-15198","GHSA-jc87-6vpp-7ff3","PYSEC-2020-121","PYSEC-2020-313"],"modified":"2023-12-06T01:00:16.515389Z","published":"2020-09-25T19:15:00Z","references":[{"type":"WEB","url":"https://github.com/tensorflow/tensorflow/releases/tag/v2.3.1"},{"type":"FIX","url":"https://github.com/tensorflow/tensorflow/commit/3cbb917b4714766030b28eba9fb41bb97ce9ee02"},{"type":"ADVISORY","url":"https://github.com/tensorflow/tensorflow/security/advisories/GHSA-jc87-6vpp-7ff3"}],"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":"3cbb917b4714766030b28eba9fb41bb97ce9ee02"}]},{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.3.1"}]}],"versions":["1.15.0","2.1.0","2.1.1","2.1.2","2.1.3","2.1.4","2.2.0","2.2.1","2.2.2","2.2.3","2.3.0"],"database_specific":{"source":"https://github.com/pypa/advisory-database/blob/main/vulns/tensorflow-cpu/PYSEC-2020-278.yaml"}}],"schema_version":"1.7.3"}
