Description

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.

Integer Overflow or Wraparound

The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
