Description

The vulnerability allows a remote attacker to steal digital assets.

The vulnerability exists due to integer overflow within the transferFrom() function of a smart contract implementation for Useless Ethereum Token (UET). A remote attacker can steal assets (e.g., transfer all victims' balances into their account) because certain computations involving _value are incorrect.

The vulnerability was dubbed "transferFlaw" and has been exploited in the wild in December 2017.
