BFBTester is great for doing quick, proactive, security checks of binary programs. BFBTester will perform checks for single and multiple argument command line overflows and environment variable overflows. Versions 2.0-BETA and higher can also watch for tempfile creation activity to alert the user of any programs using unsafe tempfile names.
