Handle

Vulnerability details

The function Auction.settleAuction() claims to override IAuction.settleAuction(), but their arguments have different data locations.

Impact

Mismatching data locations in overrides have unexpected behavior.

ethereum/solidity#10900

Tool Used

Manual code review.

Recommended Mitigation Steps

Modify the data locations of the arguments to match between Auction.settleAuction() and IAuction.settleAuction().

I agree with the finding, however, the compiler will either refuse to compile, or simply use the data location from the actual implementation of the method (Auction).

As such, I will downgrade the finding to low severity, as it has to do with improper code / documentation more so than a functionality that can actually reduce protocol availability
