CANDY Token

CANDY.addLiquidity(uint256,uint256) (#977-991) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH.value(ethAmount)(address(this),tokenAmount,0,0,address(this),block.timestamp.add(300)) (#983-990)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Ownable._lockTime (#301) is never initialized. It is used in:
- Ownable.getUnlockTime() (#352-354)

Combination 1: Reentrancy vulnerabilities + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

CANDY.swapAndLiquify(uint256) (#899-927) performs a multiplication on the result of a division:
-sharedETH = newBalance.div(4) (#917)
-transferToAddressETH(marketingAddress,sharedETH.mul(2)) (#923)
