How to fix?

Upgrade to version 0.4.1 or higher.

Overview is an a scalable, high-throughput Proof-of-Stake blockchain that is fully compatible and interoperable with Ethereum.

Affected versions of this package are vulnerable to Signature Validation Bypass. Since ethermint uses the same chainIDEpoch and signature schemes with ethereum for compatibility, a verified signature in ethereum is still valid in ethermint with the same message content and chainIDEpoch, which enables a cross-chain transaction replay attack.
