LowAllowance Double-Spend ExploitFixed
As it presently is constructed, the contract is vulnerable to the [allowance double-spend exploit](https://github.com/OpenZeppelin/openzeppelin-solidity/blob/b4f87bb8fc25fb07f73099701e39e167a3d36465/contracts/token/ERC20/ERC20.sol#L71-L78), as with other ERC20 tokens. <br /><br /> **Update:** Although the functions `increaseAllowance()` and `decreaseAllowance()` were added to mitigate this issue, they were not accompanied with tests.
LowUnlocked PragmaFixed
Every Solidity file specifies in the header a version number of the format `pragma solidity (^)0.4.*`. The caret (`^`) before the version number implies an unlocked pragma, meaning that the compiler will use the specified version _and above_, hence the term "unlocked."
