EOS smart contract exposed that the underlying asset class has overflow risk

According to intelligence from the 360Vulcan team, there are serious flaws in the underlying asset class of the EOS smart contract, and there is an overflow risk during numerical calculations. The 360Vulcan team has now reported this to the EOS official vulnerability platform.

The team also pointed out that this is related to the root cause of the overflow attack in the EOS Werewolf game that the SlowMist security team warned on July 25. After the Werewolf team contacted SlowMist, they and the 360Vulcan team audited the contract source code and found that there was an overflow problem in the asset calculation.
