If an excessively large value is specified as the starting index for an array in `_abi_decode`, it can cause the read position to overflow. This results in the decoding of values outside the intended array bounds, potentially leading to exploitations in contracts that use arrays within `_abi_decode`. This vulnerability affects 0.3.10 and earlier versions." }, { "lang": "es", "value": "Vyper es un lenguaje de contrato inteligente pit\u00f3nico para la m\u00e1quina virtual ethereum. Si se especifica un valor excesivamente grande como \u00edndice inicial para una matriz en `_abi_decode`, puede provocar que la posici\u00f3n de lectura se desborde. Esto da como resultado la decodificaci\u00f3n de valores fuera de los l\u00edmites previstos de la matriz, lo que potencialmente conduce a explotaciones en contratos que usan matrices dentro de `_abi_decode`.
