This can cause a denial of service in products using `tensorflow-serving` or other inference-as-a-service installments. Fixed were added in commits f760f88b4267d981e13f4b302c437ae800445968 and fcfef195637c6e365577829c4d67681695956e7d (both going into TensorFlow 2.2.0 and 2.3.0 but not yet backported to earlier versions). However, this was not enough, as #41097 reports a different failure mode. The issue is patched in commit adf095206f25471e864a8e63a0f1caef53a0e3a6, 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, cambiar el b\u00fafer del protocolo \"SavedModel\" de TensorFlow y alterar el nombre de las claves requeridas resulta en fallos de segmentaci\u00f3n y una corrupci\u00f3n de los datos mientras se carga el modelo. Esto puede causar una denegaci\u00f3n de servicio en productos que usan \"tensorflow-serve\" u otras cuotas de inferencia como un servicio. Los arreglos se agregaron en las commits f760f88b4267d981e13f4b302c437ae800445968 y fcfef195637c6e365577829c4d67681695956e7d (ambas en TensorFlow versiones 2.2.0 y 2.3.0 pero a\u00fan no se han actualizado a versiones anteriores). Sin embargo, esto no fue suficiente, ya que #41097 reporta un modo de fallo diferente. El problema es parcheado en el commit adf095206f25471e864a8e63a0f1caef53a0e3a6, y es publicado en TensorFlow versiones 1.15.4, 2.0.3, 2.1.2, 2.2.1 o 2.3.1"}], "lastModified": "2021-09-16T15:45:40.520", "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"}
