Descriptions

Cosmos Network Ethermint <= v0.4.0 is affected by cache lifecycle inconsistency in the EVM module. Due to the inconsistency between the Storage caching cycle and the Tx processing cycle, Storage changes caused by a failed transaction are improperly reserved in memory. Although the bad storage cache data will be discarded at EndBlock, it is still valid in the current block, which enables many possible attacks such as an "arbitrary mint token".

Cosmos Network Ethermint versiones anteriores e incluyendo a v0.4.0, está afectado por la inconsistencia del ciclo de vida de la caché en el módulo EVM. Debido a la inconsistencia entre el ciclo de almacenamiento en caché y el ciclo de procesamiento de Tx, los cambios de almacenamiento causados ??por una transacción fallida se reservan incorrectamente en la memoria. Aunque los datos de caché de almacenamiento incorrecto se descartarán en EndBlock, aún son válidos en el bloque actual, lo que permite muchos ataques posibles, como un "arbitrary mint token"
