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.

Security issue CVE-2024-2905: World-readable /etc/shadow & /etc/gshadow on Fedora CoreOS, IoT, Atomic Desktops (including Silverblue & Kinoite) (discussion.fedoraproject.org)

Current Fedora versions that were installed as Fedora 39 are affected.

It you used an rpm-ostree version of Fedora since it was on 38 or below, and upgraded to 39, you are not affected.

The update with the fix rolls out today. As a workaround you can use this

sudo chmod --verbose 0000 /etc/shadow /etc/gshadow /etc/shadow- /etc/gshadow-

It is recommended to change all credentials stored there, i.e. at least your user(s) password(s).
