Operations | Definition |
Declare | Declare operation – Specify the name and type of an object; the name, return type, and parameters of a function; or the name and type parameters of a type. |
Define | Define operation – Specify the implementation of a function; or the member objects and functions of a type. (The data of an object is specified at its initialization – see MAD and MUS.) |
Operands | Definition |
Name | Name operand – The declared identifier for an entity. |
Type | Type operand – The data type of an object – the set of allowed values (e.g., char is within [-128, 127]) and the operations allowed over them (e.g., +, *, mod). |
Causes | Definition |
Code Bug | Code Bug Type – A code operation defect – proper operands over an improper operation. A first cause for the chain of weaknesses underlying a software security vulnerability. Must be fixed to resolve the vulnerability. |
Missing Code | |
Wrong Code | |
Erroneous Code | |
Specification Bug | Specification Bug Type – A specification operation defect – proper operands over an improper operation. A first cause for the chain of weaknesses underlying a software security vulnerability. Must be fixed to resolve the vulnerability. |
Missing Modifier | |
Wrong Modifier | |
Anonymous Scope | |
Wrong Scope | |
Type Fault | Type Fault/Error Type – The the set or range of allowed values is wrong or the operations allowed on them are wrong. |
Wrong Type Resolved | Wrong Type Resolved fault/error – A data type is resolved from a wrong scope. |
Consequences | Definition |
Name Error | Name Fault/Error Type – The resolved name is wrong. |
Missing Overridden Function | Missing Overridden Function fault/error – Function implementation in a particular subclass is absent. |
Missing Overloaded Function | Missing Overloaded Function fault/error – Code for particular function parameters' data types is absent. |
Type Error | Type Fault/Error Type – The the set or range of allowed values is wrong or the operations allowed on them are wrong. |
Wrong Type | Wrong Type fault/error – A data type range or structure is not correct. |
Incomplete Type | Incomplete Type fault/error – A specific constructor, method, or overloaded function is missing. |
Wrong Generic Type | Wrong Generic Type fault/error – A generic object is instantiated via wrong type argument. |
Confused Subtype | Confused Subtype fault/error – The object invoking an overridden function is of wrong subtype data type. |
Wrong Argument Type | Wrong Argument Type fault/error – An argument to an overloaded function is of incorrect data type. |
Access Final Error | Access exploitable error type – An exploitable or undefined system behavior caused by 'name access' declaration bugs. |
Wrong Access Object | Wrong Access Object exploitable error – An unauthorized access to an object; allows access to sensitive data or to member functions. |
Wrong Access Type | Wrong Access Type exploitable error – An unauthorized access to a data type; allows access to member objects and functions. |
Wrong Access Function | Wrong Access Function exploitable error – An unauthorized access to a function; allows its execution. |
Operations Attributes | Definition |
Mechanism | Mechanism operation attribute type – Shows how the buggy/faulty operation code is performed. |
Simple | Simple operation attribute – Non-polymorphic. |
Generics | Generics operation attribute – Parameterizing by type. |
Overriding | Overriding operation attribute – Functions with the same name as one in the base type but implemented in different subtypes. |
Overloading | Overloading operation attribute – Functions with the same name in the same declaration scope, but implemented with different signature. |
Source Code | Source Code operation attribute type – Shows where the buggy/faulty operation code is in the program – in what kind of software. |
Codebase | Codebase operation attribute – The operation is in the programmer's code - in the application itself. |
Third-Party | Third-Party operation attribute – The operation is in a third-party software. |
Standard Library | Standard Library operation attribute – The operation is in the standard library for a particular programming language. |
Compiler/Interpreter | Compiler/Interpreter operation attribute – The operation is in the language processor that allows execution or creates executables (compiler, assembler, interpreter). |
Execution Space | Execution Space operation attribute type – Shows where the buggy/faulty operation code is running or with what privilege level. |
Local | Local operation attribute – The bugged code runs in an environment with access control policy with limited (local user) permission. |
Admin | Admin operation attribute – The bugged code runs in an environment with access control policy with unlimited (admin user) permission. |
Bare-Metal | Bare-Metal operation attribute – The bugged code runs in an environment without privilege control. Usually, the program is the only software running and has total access to the hardware. |
Operands Attributes | Definition |
Name Kind | Name Kind operand attribute type – Shows what the entity with this name is. |
Object | Object operand attribute – A memory region used to store data. |
Function | Function operand attribute – An organized block of code that when called takes in data, processes it, and produces a result(s). |
Data Type | Data Type operand attribute – A set of allowed values and the operations allowed over them. |
Namespace | Namespace operand attribute – An organization of entities' names, utilized to avoid names collision. |
Type Kind | Type Kind operand attribute type – Shows what the data type composition is. |
Primitive | Primitive operand attribute – A scalar data type that mimics the hardware units - e.g., int (long, short, signed), float, double, string, Boolean. A primitive data type is only language defined and is not built from other data types. |
Structure | Structure operand attribute – A composite data type - e.g., array, list, map, class. A structured data type is built from other data types and has primitive or structured members. |
