In particular, there is no validation that the `splits` tensor has the minimum required number of elements. Code uses this quantity to initialize a different data structure. Since `BatchedMap` is equivalent to a vector, it needs to have at least one element to not be `nullptr`. If user passes a `splits` tensor that is empty or has exactly one element, we get a `SIGABRT` signal raised by the operating system. The issue is patched in commit 3cbb917b4714766030b28eba9fb41bb97ce9ee02 and is released in TensorFlow version 2.3.1."}, {"lang": "es", "value": "En Tensorflow anteriores a la versi\u00f3n 2.3.1, \"RaggedCountSparseOutput\" no comprueba que los argumentos de entrada formen un tensor irregular v\u00e1lido. En particular, no existe comprobaci\u00f3n de que el tensor \"splits\" tenga el n\u00famero m\u00ednimo requerido de elementos. El c\u00f3digo usa esta cantidad para inicializar una estructura de datos diferente. Dado que \"BatchedMap\" es equivalente a un vector, necesita tener al menos un elemento para que no sea \"nullptr\". Si el usuario pasa un tensor \"splits\" que se encuentra vac\u00edo o tiene exactamente un elemento, obtenemos una se\u00f1al \"SIGABRT\" generada por el sistema operativo. El problema es parcheado en el commit 3cbb917b4714766030b28eba9fb41bb97ce9ee02 y es publicado en TensorFlow versi\u00f3n 2.3.1"}], "lastModified": "2021-11-18T17:22:46.217", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:google:tensorflow:2.3.0:*:*:*:-:*:*:*", "vulnerable": true, "matchCriteriaId": "D0A7B69E-9388-48F0-B744-49453EBAF5D5"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
