CVE-2021-25836

Cosmos Network Ethermint <= v0.4.0 is affected by cache lifecycle inconsistency in the EVM module. The bytecode set in a FAILED transaction wrongfully remains in memory(stateObject.code) and is further written to persistent store at the Endblock stage, which may be utilized to build honeypot contracts.
