'Flawfinder' looks through source code for potential security flaws in source code by using a built-in database of C/C++ functions with well-known problems, and providing a list of potential security flaws, sorted by risk, with the most potentially dangerous flaws shown first. Risk level depends on both the function and the values of the parameters of the function. It ignores text inside comments and strings.
