CVE-2018-14088

The CVE-2018-14088 issue affects the STeX White List (STE(WL)) Ethereum token smart contract. A vulnerability in withdrawToFounders() arises from an integer overflow when the owner sets amount to a large value, causing amount * 1000000000000000 to overflow. The available sources confirm the overf...

CVE-2018-14089

CVE-2018-14089 affects Virgo_ZodiacToken smart contract: the comparison bool sufficientAllowance = allowance <= _value uses =, allowing an arbitrary transfer in transferFrom without meeting the intended allowance condition. This enables an attacker to transfer from any address to their own add...

CVE-2018-14087

CVE-2018-14087 concerns the EUC Ethereum token smart contract. A root cause is an integer overflow in the fallback function when the owner sets a large buyPrice via setPrices, causing the expression msg.value * buyPrice to overflow. Documents consistently describe this vulnerability in EUC’s cont...

CVE-2018-14085

Summary: CVE-2018-14085 describes a vulnerability in a UserWallet smart contract where an attacker-supplied contract address, when added to the owner’s sweepers, can cause the sweep function to set the sweeperList to a fixed value (0x123456789). This indicates an unauthorized modification of the ...
