CodeSonar ships with library models that allow it to functions such as libc bind() that take a network address parameter. If one of these functions is called with a potentially-tainted value in the network address 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 Tainted Network Address warnings.
