Descriptions

Vyper is a pythonic Smart Contract Language for the Ethereum virtual machine. Prior to version 0.3.0, default functions don't respect nonreentrancy keys and the lock isn't emitted. No vulnerable production contracts were found. Additionally, using a lock on a `default` function is a very sparsely used pattern. As such, the impact is low. Version 0.3.0 contains a patch for the issue.

Vyper es un lenguaje de contrato inteligente pitónico para la máquina virtual Ethereum. Antes de la versión 0.3.0, las funciones predeterminadas no respetan las claves que no son de reentrada y el bloqueo no se emite. No se encontraron contratos de producción vulnerables. Además, usar un bloqueo en una función "predeterminada" es un patrón muy poco utilizado. Como tal, el impacto es bajo. La versión 0.3.0 contiene un parche para el problema.
