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.

when building RPM or DEB.

Which ones? Everything I run seems to be clear.

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

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

[–] Laser@feddit.de 2 points 7 months ago

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

I think it needs to be

rolling release (because it was caught so quickly that it hasn't made its way into any cadence based distro yet)
using the upstream Makefile task to build a RPM or DEB (because the compromised build script directly checks for that and therefore doesn't trigger for a destdir build like Gentoo’s or Arch’s)
using the upstream provided tarball as opposed to the one GitHub provides, or a git clone (because only that contains the compromised Makefile, running autotools yourself is safe)

Points 1 and 2 mean that only rolling release RPM and DEB distros like Debian Sid and Fedora are candidates. I didn't check if they use the Makefile and the compromised tarballs.
