This allows a user to pass values that can cause heap overflow errors and even leak contents of memory In the linked code snippet, all the binary strings after `ee ff` are contents from the memory stack. Since these can contain return addresses, this data leak can be used to defeat ASLR. The issue is patched in commit 0462de5b544ed4731aa2fb23946ac22c01856b80, and is released in TensorFlow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1, or 2.3.1."}, {"lang": "es", "value": "En Tensorflow versiones anteriores a 1.15.4, 2.0.3, 2.1.2, 2.2.1 y 2.3.1, el argumento \"data_splits\" de \"tf.raw_ops.StringNGrams\" carece de comprobaci\u00f3n. Esto permite a un usuario pasar valores que pueden causar errores de desbordamiento de la pila e incluso filtrar el contenido de la memoria. En el fragmento de c\u00f3digo vinculado, todas las cadenas binarias despu\u00e9s de \"ee ff\" son contenidos desde la pila de memoria. Dado que estos pueden contener direcciones de retorno, este filtrado de datos se puede utilizar para anular ASLR. El problema es parcheado en el commit 0462de5b544ed4731aa2fb23946ac22c01856b80 y es publicado en TensorFlow versiones 1.15.4, 2.0.3, 2.1.2, 2.2.1 o 2.3.1"}], "lastModified": "2021-11-18T17:27:14.957", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:google:tensorflow:*:*:*:*:-:*:*:*", "vulnerable": true, "matchCriteriaId": "EC688B44-17B7-462D-B6E3-BAAF99334782", "versionEndExcluding": "1.15.4"}, {"criteria": "cpe:2.3:a:google:tensorflow:*:*:*:*:-:*:*:*", "vulnerable": true, "matchCriteriaId": "B6271763-8DFA-4A8F-9596-F1148961ECC5", "versionEndExcluding": "2.0.3", "versionStartIncluding": "2.0.0"}, {"criteria": "cpe:2.3:a:google:tensorflow:*:*:*:*:-:*:*:*", "vulnerable": true, "matchCriteriaId": "AA3FD62B-13CB-4EB5-939F-C848DE9AE071", "versionEndExcluding": "2.1.2", "versionStartIncluding": "2.1.0"}, {"criteria": "cpe:2.3:a:google:tensorflow:*:*:*:*:-:*:*:*", "vulnerable": true, "matchCriteriaId": "029CB8A9-ED3D-486D-967C-4CE0AF8D8FAD", "versionEndExcluding": "2.2.1", "versionStartIncluding": "2.2.0"}, {"criteria": "cpe:2.3:a:google:tensorflow:*:*:*:*:-:*:*:*", "vulnerable": true, "matchCriteriaId": "B617650A-B5A1-44BB-BB3A-2EF83648B100", "versionEndExcluding": "2.3.1", "versionStartIncluding": "2.3.0"}], "operator": "OR"}]}, {"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:opensuse:leap:15.2:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "B009C22E-30A4-4288-BCF6-C3E81DEAF45A"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
