CVE-2018-14087

An issue was discovered in a smart contract implementation for EUC (EUC), an Ethereum token. The contract has an integer overflow. If the owner sets the value of buyPrice to a large number in setPrices() then the "msg.value * buyPrice" will cause an integer overflow in the fallback function.
