Summary
### Summary Minting large amount of tokens through ibc transfer and then depositing them in validator rewards pool (via `DepositValidatorRewardsPool` message) can lead to integer overflow panic when calculating `cumulative_reward_ratio` for the validator. This calculation happens in `x/epoching` module `EndBlocker`, thus the panic will halt the chain. ### Impact Denial of Service - Due to panic in the `EndBlocker` Babylon Genesis will halt
