In case you haven’t heard, this week Google announced a project called OSS-Fuzz. The basic idea of fuzz testing is take random inputs, throw them at a program, and see if it breaks. The basic idea of OSS-Fuzz is to use buttloads of servers that Google has lying around to do fuzz testing for open source. OSS-Fuzz already has an impressive trophy case of vulnerabilities found, from running over 4 trillion test cases per week.
