CERT C Secure Coding Standard (2008) Chapter 8 - Characters and Strings (STR)

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 Characters and Strings (STR) chapter of the CERT C Secure Coding Standard (2008).

Weaknesses

Addition of Data Structure Sentinel

The accidental addition of a data-structure sentinel can cause serious programming logic problems.

Buffer Copy without Checking Size of Input ('Classic Buffer Overflow')

The program copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buf...

Function Call With Incorrect Argument Type

The software calls a function, procedure, or routine, but the caller specifies an argument that is the wrong data type, which may lead to resultant weaknesses.

Improper Neutralization of Argument Delimiters in a Command ('Argument Injection')

The software constructs a string for a command to executed by a separate component in another control sphere, but it does not properly delimit the intended arguments, ...

Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

The software constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralize...

Improper Null Termination

The software does not terminate or incorrectly terminates a string or array with a null character or equivalent terminator.

Improper Restriction of Operations within the Bounds of a Memory Buffer

The software performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer.

Incorrect Calculation of Multi-Byte String Length

The software does not correctly calculate the length of strings that can contain wide or multi-byte characters.

Incorrect Type Conversion or Cast

The software does not correctly convert an object, resource, or structure from one type to a different type.

Off-by-one Error

A product calculates or uses an incorrect maximum or minimum value that is 1 more, or 1 less, than the correct value.

Concepts

Deprecated or Obsolete
