VaultOwned.setVault(address).vault_ (contracts/helpers/VaultOwned.sol#10) lacks a zero-check on :
- _vault = vault_ (contracts/helpers/VaultOwned.sol#11)
Check that the address is not zero.

Additional information: link

VaultOwned.setVault(address) (contracts/helpers/VaultOwned.sol#10-14) should emit an event for:
- _vault = vault_ (contracts/helpers/VaultOwned.sol#11)
Emit an event for critical parameter changes.

ERC20Permit.constructor() (contracts/helpers/ERC20Permit.sol#153-168) uses assembly
- INLINE ASM (contracts/helpers/ERC20Permit.sol#155-157)
Do not use evm assembly.

Additional information: link

ERC20Permit.permit(address,address,uint256,uint256,uint8,bytes32,bytes32) (contracts/helpers/ERC20Permit.sol#170-191) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp <= deadline,Permit: expired deadline) (contracts/helpers/ERC20Permit.sol#179)
Avoid relying on block.timestamp.
