What is flawfinder
flawfinder is:
Flawfinder searches through C/C++ source code looking for potential
security flaws and produces a report describing the potential flaws
found in source code, ranking them by likely severity.
Like RATS, Flawfinder reports are not a direct indication of a
vulnerability, but provide a reasonable starting point for performing manual
security audits in source code.
Flawfinder can also generate differential reports by pointing it to
a patch (diff) file describing the code changes. This way it can be used
to determine if the potential flaws found in code have increased or
decreased after a commit to a source code management system like
CVS or Subversion.
