{"id":"PYSEC-2020-298","details":"In affected versions of TensorFlow the tf.raw_ops.DataFormatVecPermute API does not validate the src_format and dst_format attributes. The code assumes that these two arguments define a permutation of NHWC. This can result in uninitialized memory accesses, read outside of bounds and even crashes. 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":["BIT-tensorflow-2020-26267","CVE-2020-26267","GHSA-c9f3-9wfr-wgh7","PYSEC-2020-140","PYSEC-2020-333"],"modified":"2023-12-06T00:45:26.701514Z","published":"2020-12-10T23:15:00Z","references":[{"type":"FIX","url":"https://github.com/tensorflow/tensorflow/commit/ebc70b7a592420d3d2f359e4b1694c236b82c7ae"},{"type":"ADVISORY","url":"https://github.com/tensorflow/tensorflow/security/advisories/GHSA-c9f3-9wfr-wgh7"}],"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":"ebc70b7a592420d3d2f359e4b1694c236b82c7ae"}]},{"type":"ECOSYSTEM","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"}]}],"versions":["1.15.0","2.1.0","2.1.1","2.1.2","2.2.0","2.2.1","2.3.0","2.3.1"],"database_specific":{"source":"https://github.com/pypa/advisory-database/blob/main/vulns/tensorflow-cpu/PYSEC-2020-298.yaml"}}],"schema_version":"1.7.3"}
