CVE-2018-13578
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe mintToken function of a smart contract implementation for GalaxyCoin, an Ethereum token, has an integer overflow that allows the owner of the contract to set the balance of an arbitrary user to any value.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceInteger overflow vulnerability in the mintToken function of the GalaxyCoin Ethereum smart contract allows the contract owner to set arbitrary user balances due to unchecked arithmetic operations.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if Galaxycoin contract is deployedQuery the blockchain for the Galaxycoin contract address and verify it exists on the network where your environment holds funds or tokensAffected if The contract is deployed and you hold Galaxycoin tokens or interact with this contract
-
Locate the mintToken function in contract sourceObtain the Galaxycoin contract source code (from Etherscan or your deployment records) and locate the mintToken function definitionAffected if The mintToken function exists in the contract code
-
Verify SafeMath is used in mintTokenInspect the mintToken function code and check whether it uses SafeMath library or implements overflow checks for all arithmetic operations (+, -, *, /)Affected if The function uses raw arithmetic operators without SafeMath or overflow validation
-
Check if contract owner can call mintTokenReview the contract code to determine if the mintToken function is callable by the contract owner and examine whether it modifies user balancesAffected if The mintToken function is accessible to the owner and directly manipulates account balances without proper checks
-
Inspect arithmetic operations for overflow vulnerabilitiesExamine each arithmetic operation in mintToken (particularly balance modifications and token minting calculations) for potential integer overflow conditionsAffected if Any arithmetic operation on balances or token amounts lacks overflow protection
You are affected if the Galaxycoin contract is deployed in your environment and the mintToken function contains unchecked arithmetic operations that could cause integer overflow when the owner mints tokens.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement SafeMath library or equivalent overflow checks for all arithmetic operations in the mintToken function and other sensitive functions.
