However, the only check that the converted index is now valid is only present in debug builds. If the `DCHECK` does not trigger, then code execution moves ahead with a negative index. This, in turn, results in accessing data out of bounds which results in segfaults and/or data corruption. The issue is patched in commit 2d88f470dea2671b430884260f3626b1fe99830a, 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-lite versiones anteriores a 1.15.4, 2.0.3, 2.1.2, 2.2.1 y 2.3.1, para imitar la indexaci\u00f3n de Python con valores negativos, TFLite usa \"ResolveAxis\" para convertir valores negativos en \u00edndices positivos. Sin embargo, la \u00fanica comprobaci\u00f3n de que el \u00edndice convertido ahora es v\u00e1lido solo est\u00e1 presente en las compilaciones de depuraci\u00f3n. Si el \"DCHECK\" no se activa, entonces la ejecuci\u00f3n de c\u00f3digo avanza con un \u00edndice negativo. Esto, a su vez, resulta en el acceso a los datos fuera de l\u00edmites, resultando en segmentaciones y/o una corrupci\u00f3n de lo datos. El problema es parcheado en el commit 2d88f470dea2671b430884260f3626b1fe99830a, y es publicado en TensorFlow versiones 1.15.4, 2.0.3, 2.1.2, 2.2.1 o 2.3.1"}], "lastModified": "2021-11-18T17:27:27.907", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:google:tensorflow:*:*:*:*:lite:*:*:*", "vulnerable": true, "matchCriteriaId": "7A5421A9-693F-472A-9A21-43950C884C77", "versionEndExcluding": "1.15.4"}, {"criteria": "cpe:2.3:a:google:tensorflow:*:*:*:*:lite:*:*:*", "vulnerable": true, "matchCriteriaId": "B0FEB74E-5E54-4A2F-910C-FA1812C73DB2", "versionEndExcluding": "2.0.3", "versionStartIncluding": "2.0.0"}, {"criteria": "cpe:2.3:a:google:tensorflow:*:*:*:*:lite:*:*:*", "vulnerable": true, "matchCriteriaId": "47D83682-6615-49BC-8043-F36B9D017578", "versionEndExcluding": "2.1.2", "versionStartIncluding": "2.1.0"}, {"criteria": "cpe:2.3:a:google:tensorflow:*:*:*:*:lite:*:*:*", "vulnerable": true, "matchCriteriaId": "323B716A-E8F7-4CDA-B8FD-A56977D59C02", "versionEndExcluding": "2.2.1", "versionStartIncluding": "2.2.0"}, {"criteria": "cpe:2.3:a:google:tensorflow:*:*:*:*:lite:*:*:*", "vulnerable": true, "matchCriteriaId": "C09502A8-B667-4867-BEBD-40333E98A601", "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"}
