A program that scans source code looking for security weaknesses
Flawfinder searches through source code looking for potential security flaws. It will provide a list of potential security flaws, sorted by risk, with the most potentially dangerous flaws shown first. This risk level depends not only on the function, but on the values of the parameters of the function. Flawfinder ignores text inside comments and strings.
