Google extended its proactive Patch Reward Program to include even more open-source software (OSS). Among them is the Android Open Source Project, which the company previously did not reveal was going to be added. Last month, Google started providing financial incentives (between $500 and $3,133.70) for proactive improvements to OSS that go beyond merely fixing a known security bug. Google said at the time it would be rolling out the program gradually, and hinted that more project types would be on the way. Less than six weeks later, the company has added the following: All the open-source components of Android: Android Open Source Project. Widely used Web servers: Apache httpd, lighttpd, nginx. Popular mail delivery services: Sendmail, Postfix, Exim, Dovecot. Virtual private networking: OpenVPN. Network time: University of Delaware NTPD.
