Category: The CERT Oracle Secure Coding Standard for Java (2011) Chapter 5 - Numeric Types and Operations (NUM)
Obsolete
Summary
Weaknesses in this category are related to rules in the Numeric Types and Operations (NUM) chapter of The CERT Oracle Secure Coding Standard for Java (2011).
Membership
| ID | Name | Description |
|---|---|---|
| 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-844 | Weaknesses Addressed by The CERT Oracle Secure Coding Standard for Java (2011) | CWE entries in this view (graph) are fully or partially eliminated by following the guidance presented in the book "The CERT Oracle Secure Coding Standard for Java" published in 2011. This view is considered obsolete as a newer version of the coding standard is available. |
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.
