CVE-2022-35936

Ethermint is an Ethereum library. In Ethermint running versions before v0.17.2, the contract selfdestruct invocation permanently removes the corresponding bytecode from the internal database storage. However, due to a bug in the DeleteAccountfunction, all contracts that used the identical bytecod...
