The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2023:7038 advisory.

    Flatpak is a system for building, distributing, and running sandboxed desktop applications on Linux.

    The following packages have been upgraded to a later upstream version: flatpak (1.10.8). (BZ#2222103)

    Security Fix(es):

    * flatpak: TIOCLINUX can send commands outside sandbox if running on a virtual console (CVE-2023-28100)

    * flatpak: Metadata with ANSI control codes can cause misleading terminal output (CVE-2023-28101)

The remote NewStart CGSL host, running version MAIN 7.02, has flatpak packages installed that are affected by multiple vulnerabilities:

  - 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)

  - Flatpak is a system for building, distributing, and running sandboxed desktop applications on Linux. in     versions before 1.10.9, 1.12.9, 1.14.6, and 1.15.8, a malicious or compromised Flatpak app could execute     arbitrary code outside its sandbox. Normally, the `--command` argument of `flatpak run` expects to be     given a command to run in the specified Flatpak app, optionally along with some arguments. However it is     possible to instead pass `bwrap` arguments to `--command=`, such as `--bind`. It's possible to pass an     arbitrary `commandline` to the portal interface `org.freedesktop.portal.Background.RequestBackground` from     within a Flatpak app. When this is converted into a `--command` and arguments, it achieves the same effect     of passing arguments directly to `bwrap`, and thus can be used for a sandbox escape. The solution is to     pass the `--` argument to `bwrap`, which makes it stop processing options. This has been supported since     bubblewrap 0.3.0. All supported versions of Flatpak require at least that version of bubblewrap. xdg-     desktop-portal version 1.18.4 will mitigate this vulnerability by only allowing Flatpak apps to create     .desktop files for commands that do not start with --. The vulnerability is patched in 1.15.8, 1.10.9,     1.12.9, and 1.14.6. (CVE-2024-32462)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote CentOS Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the flatpak-1.12.8-1.el9 build changelog.

  - 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`.

  - Flatpak is a system for building, distributing, and running sandboxed desktop applications on Linux. In     versions prior to 1.10.8, 1.12.8, 1.14.4, and 1.15.4, if an attacker publishes a Flatpak app with elevated     permissions, they can hide those permissions from users of the `flatpak(1)` command-line interface by     setting other permissions to crafted values that contain non-printable control characters such as `ESC`. A     fix is available in versions 1.10.8, 1.12.8, 1.14.4, and 1.15.4. As a workaround, use a GUI like GNOME     Software rather than the command-line interface, or only install apps whose maintainers you trust.
