1. Brute Force Binary Tester BFBTester is great for doing quick, proactive, security checks of binary programs. BFBTester will perform checks of single and multiple argument command line overflows as well as environment variable overflows. BFBTester can also watch for tempfile creation activity to alert the user of any programs using unsafe tempfile names. While BFBTester can not test all overflows in software, it is useful for detecting initial mistakes that can red flag dangerous software. From Debian 3.0r0 APT
