Integer overflow

The mintToken function of a smart contract implementation for ZPEcoin, an Ethereum token, has an integer overflow that allows the owner of the contract to set the balance of an arbitrary user to any value...

Aurora IDEX Membership(IDXM), ERC20 Token, allows attackers to acquire contract ownership (CVE-2018–10666)

Abstract I found a new vulnerability in smart contract of IDXM Token CVE-2018–106661. Attackers can acquire contract ownership because the setOwner function is delcared as public. A new owner can subsequently bypass intended access restrictions by, for example, calling uploadBalances. Details In...
