Insecure Ownership Management in DNSSECImpl.sol

Lines of code Vulnerability details Impact This finding highlights a potential security risk related to the lack of safeguards when changing ownership in the DNSSECImpl.sol contract. As it stands, the current implementation allows for the owner to be set to address0, which could result in the los...

Interpretation Conflict

@openzeppelin/contracts is vulnerable to Interpretation Conflict. The vulnerability exists because the TransparentUpgradeableProxy clashing selector calls may not be delegated if the clashing function has a different signature with incompatible ABI encoding, which could lead to proxy revert while...

Signature malleability for S

Lines of code Vulnerability details Impact Ethereum contracts often assumes that the signature is unique, but signatures can be altered without the possession of the private key and still be valid. The EVM specification defines several so-called ‘precompiled’ contracts one of them being ecrecover...

Position ownership could be transferred to zero address

Lines of code Vulnerability details Impact Ownership of a Position could be transferred to zero address. This is usually caused by mistake but the consequence is loss of collateral. Proof of Concept The position owner calls transferOwnership but accidentally set newOwner address to 0x0. Tools Use...
