      "value": "The evm crate is a pure Rust implementation of Ethereum Virtual Machine. In `evm` crate `< 0.31.0`, `JUMPI` opcode's condition is checked after the destination validity check. However, according to Geth and OpenEthereum, the condition check should happen before the destination validity check. This is a **high** severity security advisory if you use `evm` crate for Ethereum mainnet. In this case, you should update your library dependency immediately to on or after `0.31.0`. This is a **low** severity security advisory if you use `evm` crate in Frontier or in a standalone blockchain, because there's no security exploit possible with this advisory. It is **not** recommended to update to on or after `0.31.0` until all the normal chain upgrade preparations have been done. If you use Frontier or other `pallet-evm` based Substrate blockchain, please ensure to update your `spec_version` before updating this. For other blockchains, please make sure to follow a hard-fork process before you update this."

      "value": "La crate evm es una implementaci\u00f3n pura de Rust de la m\u00e1quina virtual de Ethereum. En \"evm\" crate \"versiones anteriores a 0.31.0\", la condici\u00f3n del opcode \"JUMPI\" se comprueba despu\u00e9s de la comprobaci\u00f3n de validez del destino. Sin embargo, de acuerdo con Geth y OpenEthereum, la comprobaci\u00f3n de la condici\u00f3n debe ocurrir antes de la comprobaci\u00f3n de la validez del destino. Este es un aviso de seguridad **elevada** si usas la crate \"evm\" para la mainnet de Ethereum. En este caso, debe actualizar su dependencia de la biblioteca inmediatamente a la versi\u00f3n \"0.31.0\" o posterior. Este es un aviso de seguridad de **baja** gravedad si usas \"evm\" crate en Frontier o en una blockchain independiente, porque no se presenta ninguna explotaci\u00f3n de seguridad posible con este aviso. No se recomienda actualizar a la versi\u00f3n \"0.31.0\" o posterior hasta que se hayan realizado todos los preparativos normales de actualizaci\u00f3n de la cadena. Si usa Frontier u otra cadena de bloques basada en \"pallet-evm\", aseg\u00farese de actualizar su \"spec_version\" antes de actualizar esto. Para otras blockchains, por favor aseg\u00farese de seguir un proceso de hard-fork antes de actualizar esto"
