Summary

The contract multiplies oracle data by a power of 10 without thoroughly
checking for potential overflow conditions. While the comment indicates this is
'extremely improbable', it still represents a mathematical risk.

Vulnerability Details

Location: ChainlinkOracle.sol (lines 39-39)

The contract multiplies oracle data by a power of 10 without thoroughly
checking for potential overflow conditions. While the comment indicates this is
'extremely improbable', it still represents a mathematical risk.

Code Snippet:
data = data * int(10 ** normalizationFactor);

Prevention:
Use SafeMath library for Solidity < 0.8.0
Use Solidity 0.8.0+ with built-in overflow checks
Add explicit bounds checking

Impact

Incorrect calculations leading to fund loss or broken contract logic.

Tools Used

Recommendations

Implement explicit bounds checking before multiplication or use a
SafeMath-style library for the multiplication operation, even though Solidity 0.8+
includes overflow checks.
