Integer overflow vulnerability in payable function of a smart contract implementation for an Ethereum token, as demonstrated by the smart contract implemented at address 0xB49E984A83d7A638E7F2889fc8328952BA951AbE, an implementation for MillionCoin (MON).
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.
