SAUDIDOGE Token

SaudiDoge.swapBack() (#457-503) sends eth to arbitrary user
Dangerous calls:
- (tmpSuccess) = address(marketingFeeReceiver).call{value: amountBNBMarketing}() (#485)
- (tmpSuccess,None) = address(utilityFeeReceiver).call{value: amountBNButility}() (#486)
- (tmpSuccess,None) = address(devFeeReceiver).call{value: amountBNBdev}() (#487)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

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.

Contract ownership is not renounced (belongs to a wallet)

SaudiDoge.takeFee(address,uint256,address) (#384-408) performs a multiplication on the result of a division:
-feeAmount = amount.mul(totalFee).mul(multiplier).div(feeDenominator * 100) (#394)
-stakingTokens = feeAmount.mul(stakingFee).div(totalFee) (#396)
Consider ordering multiplication before division.

Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.
