      "value": "Vyper is a pythonic Smart Contract Language for the ethereum virtual machine. 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."

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`. Esta vulnerabilidad afecta a la versi\u00f3n 0.3.10 y versiones anteriores."
