Summary

flatpak security update

Details

flatpak is a system for building, distributing and running sandboxed desktop applications on Linux. See https://wiki.gnome.org/Projects/SandboxedApps for more information.

Security Fix(es):

A vulnerability, which was classified as very critical, has been found in Flatpak up to 1.10.7/1.12.7/1.14.3/1.15.3.Using CWE to declare the problem leads to CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.Impacted is confidentiality, integrity, and availability.Upgrading to version 1.10.8, 1.12.8, 1.14.4 or 1.15.4 eliminates this vulnerability.(CVE-2023-28100)

CVE-2023-28100 (GCVE-0-2023-28100)

Vulnerability from cvelistv5 – Published: 2023-03-16 15:51 – Updated: 2025-02-13 16:45

Title

TIOCLINUX can send commands outside sandbox if running on a virtual console

Summary

Flatpak is a system for building, distributing, and running sandboxed desktop applications on Linux. Versions prior to 1.10.8, 1.12.8, 1.14.4, and 1.15.4 contain a vulnerability similar to CVE-2017-5226, but using the `TIOCLINUX` ioctl command instead of `TIOCSTI`. If a Flatpak app is run on a Linux virtual console such as `/dev/tty1`, it can copy text from the virtual console and paste it into the command buffer, from which the command might be run after the Flatpak app has exited. Ordinary graphical terminal emulators like xterm, gnome-terminal and Konsole are unaffected. This vulnerability is specific to the Linux virtual consoles `/dev/tty1`, `/dev/tty2` and so on. A patch is available in versions 1.10.8, 1.12.8, 1.14.4, and 1.15.4. As a workaround, don't run Flatpak on a Linux virtual console. Flatpak is primarily designed to be used in a Wayland or X11 graphical environment.
