Commit 77a294d

Update maintainer and author info. The other maintainer suddenly disappeared.

Lmao, that’s putting it lightly.

I like how the first point made is that the backdoor violates the Debian Free Software Guidelines, as if that’s the main problem

the other maintainer now has a special place:

Special author: Jia Tan was a co-maintainer in 2022-2024. He and the team behind him inserted a backdoor (CVE-2024-3094) into XZ Utils 5.6.0 and 5.6.1 releases. He suddenly disappeared when this was discovered.

I don’t think they would be in much peace. It was years of their work that was ruined by a person with OCD and valgrind.

I wonder if he has a donation page. We need to get him some money.

I wrote to ask him but I never heard back. To be fair he’s probably quite stressed at the moment.

I agree we should support him, but you know who should be more concerned with giving him and other open source maintainers money? The billion dollar corporations that rely on these critical projects and use them absolutely for free. Amazon, Microsoft, Sony, Samsung, Google, Siemens, Motorola, God knows how many more.

I bet Samsung would not even know if open source is a thing

Samsung is the primary developer for Tizen, a Linux based OS similar to Android. Their watches, cameras, and TVs run it.

I gotta hand it to Samsung that they outline all the open source licences they use, at least in their Galaxy smartphone products:

He probably needs a comaintainer. We could select one of us and then try pressuring him into accepting that.

We need more non profits who can set aside funds for these projects. It not like these companies don’t want to help its just jot entirely clear how they can help.

They can help by donating some of their billions.

But when open source projects go dual license to try and get paid people lose their minds.

People, stop celebrating “freeing” software of maintainers that want to prevent being exploited.

Can someone provide a summary on what this means? I thought there were malicious exploits in this. Why is it back up and the perpetrator unbanned?

It’s just a question. Any implications or tone you perceive here is likely your own projection.

Try and read it assuming the poster is asking in good faith.

Lasse is the original maintainer of XZ, they have been placed back in their position as sole maintainer.

“Jia Tan” was the person who slipped the backdoor into XZ and is now banned.

Lasse has already fixed abd removed the backdoor.

XZ itself is critical software everyone uses (its one of the main compression/decompression programs used on linux)

Yes but damage seems to be done. Distros are talking or have moved off of it to zstd.

Zstd and xz fullfil different needs. Xz take more time to compress and is faster to decompress as far as I know.

I would argue this might make xz safer mid-term. So much eyes on it. I’m not familiar with other solutions, but who’s to say the bad actor won’t try a similar trick elsewhere

There are some, probably. But any exodus will be slow. Xz isn’t useless because it was dangerous once.

Exploits were removed. Maintainer who committed them still banned. xz is a critical piece of software.

Lasse Collin is not the perpetrator, that would be “Jia Tan”.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Rules

  • Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.
  • No misinformation
  • No NSFW content
  • No hate speech, bigotry, etc
