- lockList[receiver].push(item) (#439)
CarbonToken (#362-615) contract sets array length with a user-controlled value:
- lockList[receiver].push(item) (#611)
Do not allow array lengths to be set directly set; instead, opt to add values as needed. Otherwise, thoroughly review the contract to ensure a user-controlled variable cannot reach an array length assignment.
