Backdoor only gets inserted when building RPM or DEB. So while updating frequently is a good idea, it won’t change anything for Arch users today.

when building RPM or DEB.

Which ones? Everything I run seems to be clear.

https://access.redhat.com/security/cve/CVE-2024-3094

Products / Services Components State
Enterprise Linux 6 xz Not affected
Enterprise Linux 7 xz Not affected
Enterprise Linux 8 xz Not affected
Enterprise Linux 9 xz Not affected

(and thus all the bug-for-bug clones)

Fedora 41, Fedora Rawhide, Debian Sid are the currently known affected ones AFAIK.

Those getting the most recent software versions, so nothing that should be running in a server.

Archlinux’s XZ was compromised as well.

I think that was a precaution. The malicious build script ran during the build, but the backdoor itself was most likely not included in the resuling package as it checked for specific packaging systems.

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.

  • Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.
