CVE-2018-12068

The sell function of a smart contract implementation for Target Coin TGT, a tradable Ethereum ERC20 token, allows a potential trap that could be used to cause financial damage to the seller, because of overflow of the multiplication of its argument amount and a manipulable variable sellPrice, aka...

CVE-2018-12068

The CVE-2018-12068 issue concerns a math overflow in the sell() function of the Target Coin (TGT) ERC20 contract. The vulnerability arises from overflow in multiplying the argument amount by a manipulable sellPrice, enabling a potential trap (tradeTrap) that could cause financial damage to the se...

CVE-2018-12083

The CVE-2018-12083 entry concerns GOAL Bonanza (GOAL), an Ethereum ERC20 token whose smart-contract mintToken function has no period constraint, enabling the owner to arbitrarily increase total supply. This minting oversight creates a supply manipulation risk described as the tradeTrap. Affected ...
