MasterChef.safeTokenTransfer(address,uint256) (#1479-1486) ignores return value by token.transfer(_to,_amount) (#1484)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

MasterChef.updatePool(uint256) (#1406-1422) uses a dangerous strict equality:
- lpSupply == 0 || pool.allocPoint == 0 (#1412)
Don't use strict equality to determine if an account has enough Ether or tokens.

Additional information: link

MasterChef.updatePool(uint256) (#1406-1422) performs a multiplication on the result of a division:
-tokenReward = multiplier.mul(tokenPerBlock).mul(pool.allocPoint).div(totalAllocPoint) (#1417)
-pool.accTokenPerShare = pool.accTokenPerShare.add(tokenReward.mul(1e12).div(lpSupply)) (#1420)
Consider ordering multiplication before division.

Token.delegateBySig(address,uint256,uint256,uint8,bytes32,bytes32) (#1098-1139) uses timestamp for comparisons
Dangerous comparisons:

Avoid relying on block.timestamp.
