Numeric Errors
A category in the Common Weakness Enumeration published by The MITRE Corporation.
Summary
Categories in the Common Weakness Enumeration (CWE) group entries based on some common characteristic or attribute.
Weaknesses in this category are related to improper calculation or conversion of numbers.
Weaknesses
The product divides a value by zero.
An integer value is specified to be shifted by a negative amount or an amount greater than or equal to the number of bits contained in the value causing an unexpected ...
When converting from one data type to another, such as long to integer, data can be omitted or translated in a way that produces unexpected values. If the resulting va...
The product parses numeric input assuming base 10 (decimal) values, but it does not account for inputs that use a different base number (radix).
The product processes a real number with an implementation in which the number's representation does not preserve required accuracy and precision in its fractional par...
The 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 o...
The product subtracts one value from another, such that the result is less than the minimum allowable integer value, which produces a value that is not equal to the co...
The product checks a value to ensure that it is less than or equal to a maximum, but it does not also verify that the value is greater than or equal to the minimum.
A product calculates or uses an incorrect maximum or minimum value that is 1 more, or 1 less, than the correct value.
Wrap around errors occur whenever a value is incremented past the maximum value for its type and therefore "wraps around" to a very small, negative, or undefined value.
Concepts
This view organizes weaknesses around concepts that are frequently used or encountered in software development. This includes all aspects of the software development l...
