Amazon Linux 2 : flatpak (ALAS-2023-2134)
medium Nessus Plugin ID 178541
Language:
Synopsis
The remote Amazon Linux 2 host is missing a security update.Description
The version of flatpak installed on the remote host is prior to 1.0.9-10. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2023-2134 advisory.- 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. (CVE-2023-28100)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
