One of the primary responsibilities of a maintainer is to ensure the security of the software. If they can't keep up with the pace of development in order to ensure this for their users, then this should be made clear to the community, and a decision should be made about how to proceed. Open source maintenance is an often stressful and thankless role, but this is part of the problem that allowed this to happen. Sure, a sophisticated attacker would be able to fool the eyes of a single tired maintainer, but the chances of that happening are much smaller if there's a stringent high bar of minimum quality, and at least one maintainer understands the code that is being merged in. Change proposals should never be blindly approved, regardless of who they come from. At the end of the day we have to be able to answer why this happened, and how we can prevent it from happening again. It's not about pointing fingers, but about improving the process. BTW, there have been several attempts at introducing backdoors in the Linux kernel. Some manage to go through, and perhaps we don't know about others, but many were thwarted due to the extreme vigilance of maintainers. Thankfully so, as everyone is well aware of how critical the project is. I'm not saying that all projects have the resources and visibility of Linux, but clearly vigilance is a requirement for lowering the chances of this happening. > That's assuming a maintainer wasn't compromised, like in this case. What makes you say that? Everything I've read about this (e.g. [1]) suggests that this was done by someone who also made valid contributions and gained gradual control of the project, where they were allowed to bypass any checks, if they existed at all. The misplaced trust in external contributions, and the lack of a proper peer review process are precisely what allowed this to happen.
