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.

Bad title. This is CVE-2024-3094. Run "xz --version" to see if you are affected.

"Run the affected binary to see if you have it"

AFAIK it‘s better to use rpm -q xz xz-libs (copied from the forum replies) to avoid running xz itself just in case the affected version is already installed

If you go to the post, on the comments, there is someone that is already telling you to run dnf list xz --installed. So you don't need to run xz directly.

Yeah that's just the title from the thread over on the Fedora forum

Can't you edit it?

[–] [email protected] 1 points 7 months ago

Yes but that would be disingenuous. The current title better captures the urgency of the situation

If you are checking out the extent of damage on your system do not use ldd to check the links.

You can inadvertently executed the exploit this way.
