Automated Static Analysis

Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then searching for potentially-vulnerable patterns that connect "sources" (origins of input) with "sinks" (destinations where the data interacts with external components, a lower layer such as the OS, etc.)
Effectiveness : High

Vulnerability Mapping Notes

Justification : This CWE entry is at the Base level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.
Comment : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.

NotesNotes

The Linux Standard Base Specification 2.0.1 for libc places constraints on the arguments to some internal functions [21]. If the constraints are not met, the behavior of the functions is not defined. It is unusual for this function to be called directly. It is almost always invoked through a macro defined in a system header file, and the macro ensures that the following constraints are met: The value 1 must be passed to the third parameter (the version number) of the following file system function: __xmknod The value 2 must be passed to the third parameter (the group argument) of the following wide character string functions: __wcstod_internal __wcstof_internal __wcstol_internal __wcstold_internal __wcstoul_internal The value 3 must be passed as the first parameter (the version number) of the following file system functions: __xstat __lxstat __fxstat __xstat64 __lxstat64 __fxstat64
