SEI CERT C Coding Standard - Guidelines 12. Error Handling (ERR)

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 the rules and recommendations in the Error Handling (ERR) section of the SEI CERT C Coding Standard.

Weaknesses

Incorrect Check of Function Return Value

The software incorrectly checks a return value from a function, which prevents the software from detecting errors or exceptional conditions.

Missing Initialization of a Variable

The software does not initialize critical variables, which causes the execution environment to use unexpected values.

Reliance on Undefined, Unspecified, or Implementation-Defined Behavior

The software uses an API function, data structure, or other entity in a way that relies on properties that are not always guaranteed to hold for that entity.

Unchecked Error Condition

[PLANNED FOR DEPRECATION. SEE MAINTENANCE NOTES.] Ignoring exceptions and other error conditions may allow an attacker to induce unexpected behavior unnoticed.

Unchecked Return Value

The software does not check the return value from a method or function, which can prevent it from detecting unexpected states and conditions.

Use of Potentially Dangerous Function

The program invokes a potentially dangerous function that could introduce a vulnerability if it is used incorrectly, but the function can also be used safely.
