Flawfinder examines source code and reports possible security weaknesses (``flaws'') sorted by risk level. It's very useful for quickly finding and removing at least some potential security problems before a program is widely released to the public.This app doesn't have any features at the moment.
Splint is a tool for statically checking C programs for security vulnerabilities and coding mistakes. With minimal effort, Splint can be used as a better lint. If additional effort is invested adding annotations to programs, Splint can perform stronger checking than can be done...Discontinued
