Weaknesses
CWE · root cause- CWE-189Numeric ErrorsWeaknesses in this category are related to improper calculation or conversion of numbers.
- CWE-190Integer Overflow or WraparoundThe product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
