In particular, there is no validation that the values in the `splits` tensor generate a valid partitioning of the `values` tensor. Hence, the code is prone to heap buffer overflow. If `split_values` does not end with a value at least `num_values` then the `while` loop condition will trigger a read outside of the bounds of `split_values` once `batch_idx` grows too large. 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, la implementaci\u00f3n de \"RaggedCountSparseOutput\" no comprueba que los argumentos de entrada formen un tensor irregular v\u00e1lido. En particular, no existe comprobaci\u00f3n de que los valores en el tensor \"splits\" generen una partici\u00f3n v\u00e1lida del tensor \"values\". Por lo tanto, el c\u00f3digo es propenso a un desbordamiento del b\u00fafer de la pila. Si \"split_values\" no termina con un valor de al menos \"num_values\", entonces la condici\u00f3n de bucle \"while\" activar\u00e1 una lectura fuera de los l\u00edmites de \"split_values\" una vez que \"batch_idx\" se incremente demasiado. El problema es parcheado en el commit 3cbb917b4714766030b28eba9fb41bb97ce9ee02 y es publicado en TensorFlow versi\u00f3n 2.3.1"}], "lastModified": "2021-11-18T17:24:50.060", "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"}
