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.

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?
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.
XZ is a slog to compress and decompress but compresses a bit smaller than zstd.
zstd is quite quick to compress, very quick to decompress, scales to many cores (vanilla xz is single-core only) and scales a lot further in the quicker end of the compression speed <-> file size trade-off spectrum while using the same format.
