Description

This security bulletin contains information about 1 vulnerability.


1) Integer overflow (CVE-ID: CVE-2018-10468)

CWE-ID: CWE-190 - Integer overflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:L/SC:N/SI:N/SA:N/E:A/U:Amber


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.
