Category: SEI CERT Oracle Secure Coding Standard for Java - Guidelines 03. Numeric Types and Operations (NUM)
Stable
Summary
Weaknesses in this category are related to the rules and recommendations in the Numeric Types and Operations (NUM) section of the SEI CERT Oracle Secure Coding Standard for Java.
Membership
| ID | Name | Description |
|---|---|---|
| CWE-190 | Integer Overflow or Wraparound | Integer overflow or wraparound occurs when a calculation produces a numeric result that exceeds the maximum value a variable can hold. Instead of increasing as expected, the value wraps around to a very small or negative number, breaking the program's logic. |
| CWE-191 | Integer Underflow (Wrap or Wraparound) | Integer underflow occurs when a subtraction operation results in a value smaller than the data type's minimum limit, causing the value to wrap around to a large, incorrect number. |
| CWE-197 | Numeric Truncation Error | A numeric truncation error happens when a program converts a number to a smaller data type, cutting off its higher-order bits and corrupting the original value. |
| CWE-369 | Divide By Zero | A divide-by-zero error occurs when software attempts to perform a division operation where the denominator is zero. |
| CWE-681 | Incorrect Conversion between Numeric Types | This vulnerability occurs when a program converts a value from one numeric type to another (like a 64-bit integer to a 32-bit integer) and the conversion loses or misinterprets data. If these corrupted values are later used in security-critical operations—like calculating buffer sizes, checking permissions, or performing financial transactions—they can lead to crashes, incorrect behavior, or security bypasses. |
| CWE-682 | Incorrect Calculation | This vulnerability occurs when software performs a calculation that produces wrong or unexpected results, which are then used to make security decisions or manage critical resources. |
| CWE-1133 | Weaknesses Addressed by the SEI CERT Oracle Coding Standard for Java | CWE entries in this view (graph) are fully or partially eliminated by following the guidance presented in the online wiki that reflects that current rules and recommendations of the SEI CERT Oracle Coding Standard for Java. |
Vulnerability Mapping Notes
Usage: Prohibited
Reasons: Category
Rationale:
This entry is a Category. Using categories for mapping has been discouraged since 2019. Categories are informal organizational groupings of weaknesses that can help CWE users with data aggregation, navigation, and browsing. However, they are not weaknesses in themselves.
