The malicious changes were submitted by JiaT75, one of the two main xz Utils developers with years of contributions to the project.
“Given the activity over several weeks, the committer is either directly involved or there was some quite severe compromise of their system,” an official with distributor OpenWall wrote in an advisory. “Unfortunately the latter looks like the less likely explanation, given they communicated on various lists about the ‘fixes’” provided in recent updates. Those updates and fixes can be found here, here, here, and here.
On Thursday, someone using the developer’s name took to a developer site for Ubuntu to ask that the backdoored version 5.6.1 be incorporated into production versions because it fixed bugs that caused a tool known as Valgrind to malfunction.
“This could break build scripts and test pipelines that expect specific output from Valgrind in order to pass,” the person warned, from an account that was created the same day.
One of maintainers for Fedora said Friday that the same developer approached them in recent weeks to ask that Fedora 40, a beta release, incorporate one of the backdoored utility versions.
“We even worked with him to fix the valgrind issue (which it turns out now was caused by the backdoor he had added),” the Ubuntu maintainer said.
He has been part of the xz project for two years, adding all sorts of binary test files, and with this level of sophistication, we would be suspicious of even older versions of xz until proven otherwise.
Nothing about the portion of the sentence you highlight actually implies that they haven’t already been getting paid to do open source work. That’s an interpretation that you’re projecting onto the sentence because it fits your narrative. The poster never identified themself to be a volunteer. I’ve already reframed the sentence for you in a previous post, but I’ll try one more time: “Whenever any tech company is willing to pay me to do work related to my open source project, I sit down with them and talk about my rates” is a semantically equivalent sentence to what the poster said.
You’re also taking one single datapoint which has ambiguous credibility to begin with and extrapolating it to characterize a massive industry that you, like countless others, benefit from while hardly knowing anything about how the sausage gets made.
I’d be surprised if you’ve ever offered a substantive contribution to an open source project in your life, so I won’t be losing any sleep if a freeloader loses confidence in the ecosystem. But realistically you’ll be using open source software for the rest of your life because the reality is that closed source software really can’t compete in terms of scale, impact, and accessibility. If you actually care about the quality and security of the things you depend on, then do something about it. And prattling ignorance on social media does not count as doing something.
Sorry, realize I told you I was done with our conversation, but after doing so I stumbled upon this video, and thought I would share it with you, as its pertinent to the issue we were discussing.
You keep arguing that open source projects are strict with their code base reviews and such and are as reliable as close sourced products, and I keep seeing others saying that they are not suppliers, and everything is “as is”. We can’t both be right.
I don’t plan on responding to you if you reply to this comment, as IMHO it would be a waste of time, as you’ll just twist this video so that its saying the opposite of what its actually saying.
Go ahead and quote the words I said that suggest this. You have a talent for claiming that people have said things they have never actually said.
The only claims I’ve made in this conversation are:
