![]() It is possible for unspecified values to result in a buffer overflow, leading to the execution of arbitrary code by an attacker. As with the noncompliant code example, this compliant solution does not allow a nested name specifier and will implicitly convert the enumerator value to int. The previous compliant solution requires a nested name specifier to identify the enumerator (for example, EnumType::First) and will not implicitly convert the enumerator value to int. On a two's complement system, the valid range of values that can be represented by EnumType are, so if a value outside of that range were passed to f(), the cast to EnumType would result in an unspecified value, and using that value within the if statement results in unspecified behavior.Īlthough similar to the previous compliant solution, this compliant solution differs from the noncompliant code example in the way the enumerator values are expressed in code and which implicit conversions are allowed. This noncompliant code example attempts to check whether a given value is within the range of acceptable enumeration values. However, it is doing so after casting to the enumeration type, which may not be able to represent the given integer value. Noncompliant Code Example (Bounds Checking) When dynamically checking for out-of-range values, checking must be performed before the cast expression. To avoid operating on unspecified values, the arithmetic value being cast must be within the range of values the enumeration can represent. The resulting value is the same as converting the original value to the underlying type of the enumeration ( 7.3.10 ), and subsequently to the enumeration type. A value of floating-point type can also be explicitly converted to an enumeration type. If the enumeration type does not have a fixed underlying type, the value is unchanged if the original value is within the range of the enumeration values ( 9.7.1 ), and otherwise, the behavior is undefined. If the enumeration type has a fixed underlying type, the value is first converted to that type by integral conversion, if necessary, and then to the enumeration type. The C++ Standard,, paragraph 10, states the following:Ī value of integral or enumeration type can be explicitly converted to a complete enumeration type. If the enumerator-list is empty, the values of the enumeration are as if the enumeration had a single enumerator with value 0. It is possible to define an enumeration that has values not defined by any of its enumerators. The width of the smallest bit-field large enough to hold all the values of the enumeration type is M. Otherwise, the values of the enumeration are the values representable by a hypothetical integer type with minimal width M such that all enumerators can be represented. ![]() The range of values that can be represented by either form of enumeration may include enumerator values not specified by the enumeration itself. The range of valid enumeration values for an enumeration type is defined by the C++ Standard,, in paragraph 8 :įor an enumeration whose underlying type is fixed, the values of the enumeration are the values of the underlying type. 0.08s gpulist v4.Enumerations in C++ come in two forms: scoped enumerations in which the underlying type is fixed and unscoped enumerations in which the underlying type may or may not be fixed. #9 got benchmark programm data, about to get FAL images +0.01s. #8 Created sortOrder for cached benchmark data +0s. #7 Loaded cached benchmark data tx_nbc2_gpu_cache_values +0s. #6 found 2263 cached benchmark values +0.01s. #4 Cache table found with all needed fields in it! +0s. #3 Cache table for values found, checking fields. # started gpulist at took 0s on source +0s.
