CodeSonar ships with library models that allow it to recognize functions such as libc dlopen() and Win32 LoadLibraryA() that take a library name parameter. If one of these functions is called with a tainted value in the library name parameter position, a warning will be issued.
If you have created a custom library model for some function f() in terms of one of these existing models, calls to f() will also be capable of triggering Library Injection warnings.
The following configuration file parameters affect checks for this warning class.
