Description
The transferFrom function of a smart contract implementation for Useless Ethereum Token (UET), an Ethereum ERC20 token, allows attackers to steal assets (e.g., transfer all victims' balances into their account) because certain computations involving _value are incorrect, as exploited in the wild starting in December 2017, aka the "transferFlaw" issue.
