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.

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. 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.

The remote host is affected by the vulnerability described in GLSA-202312-12 (Flatpak: Multiple Vulnerabilities)

  - Flatpak is a system for building, distributing, and running sandboxed desktop applications on Linux. In     Flatpack since version 0.9.4 and before version 1.10.2 has a vulnerability in the file forwarding     feature which can be used by an attacker to gain access to files that would not ordinarily be allowed by     the app's permissions. By putting the special tokens `@@` and/or `@@u` in the Exec field of a Flatpak     app's .desktop file, a malicious app publisher can trick flatpak into behaving as though the user had     chosen to open a target file with their Flatpak app, which automatically makes that file available to the     Flatpak app. This is fixed in version 1.10.2. A minimal solution is the first commit `Disallow @@ and @@U     usage in desktop files`. The follow-up commits `dir: Reserve the whole @@ prefix` and `dir: Refuse to     export .desktop files with suspicious uses of @@ tokens` are recommended, but not strictly required. As a     workaround, avoid installing Flatpak apps from untrusted sources, or check the contents of the exported     `.desktop` files in `exports/share/applications/*.desktop` (typically     `~/.local/share/flatpak/exports/share/applications/*.desktop` and     `/var/lib/flatpak/exports/share/applications/*.desktop`) to make sure that literal filenames do not follow     `@@` or `@@u`. (CVE-2021-21381)

  - Flatpak is a system for building, distributing, and running sandboxed desktop applications on Linux. In     versions prior to 1.10.4 and 1.12.0, Flatpak apps with direct access to AF_UNIX sockets such as those used     by Wayland, Pipewire or pipewire-pulse can trick portals and other host-OS services into treating the     Flatpak app as though it was an ordinary, non-sandboxed host-OS process. They can do this by manipulating     the VFS using recent mount-related syscalls that are not blocked by Flatpak's denylist seccomp filter, in     order to substitute a crafted `/.flatpak-info` or make that file disappear entirely. Flatpak apps that act     as clients for AF_UNIX sockets such as those used by Wayland, Pipewire or pipewire-pulse can escalate the     privileges that the corresponding services will believe the Flatpak app has. Note that protocols that     operate entirely over the D-Bus session bus (user bus), system bus or accessibility bus are not affected     by this. This is due to the use of a proxy process `xdg-dbus-proxy`, whose VFS cannot be manipulated by     the Flatpak app, when interacting with these buses. Patches exist for versions 1.10.4 and 1.12.0, and as     of time of publication, a patch for version 1.8.2 is being planned. There are no workarounds aside from     upgrading to a patched version. (CVE-2021-41133)

  - Flatpak is a Linux application sandboxing and distribution framework. Prior to versions 1.12.3 and 1.10.6,     Flatpak doesn't properly validate that the permissions displayed to the user for an app at install time     match the actual permissions granted to the app at runtime, in the case that there's a null byte in the     metadata file of an app. Therefore apps can grant themselves permissions without the consent of the user.
    Flatpak shows permissions to the user during install by reading them from the xa.metadata key in the     commit metadata. This cannot contain a null terminator, because it is an untrusted GVariant. Flatpak     compares these permissions to the *actual* metadata, from the metadata file to ensure it wasn't lied to.
    However, the actual metadata contents are loaded in several places where they are read as simple C-style     strings. That means that, if the metadata file includes a null terminator, only the content of the file     from *before* the terminator gets compared to xa.metadata. Thus, any permissions that appear in the     metadata file after a null terminator are applied at runtime but not shown to the user. So maliciously     crafted apps can give themselves hidden permissions. Users who have Flatpaks installed from untrusted     sources are at risk in case the Flatpak has a maliciously crafted metadata file, either initially or in an     update. This issue is patched in versions 1.12.3 and 1.10.6. As a workaround, users can manually check the     permissions of installed apps by checking the metadata file or the xa.metadata key on the commit metadata.
    (CVE-2021-43860)

  - Flatpak is a Linux application sandboxing and distribution framework. A path traversal vulnerability     affects versions of Flatpak prior to 1.12.3 and 1.10.6. flatpak-builder applies `finish-args` last in the     build. At this point the build directory will have the full access that is specified in the manifest, so     running `flatpak build` against it will gain those permissions. Normally this will not be done, so this is     not problem. However, if `--mirror-screenshots-url` is specified, then flatpak-builder will launch     `flatpak build --nofilesystem=host appstream-utils mirror-screenshots` after finalization, which can lead     to issues even with the `--nofilesystem=host` protection. In normal use, the only issue is that these     empty directories can be created wherever the user has write permissions. However, a malicious application     could replace the `appstream-util` binary and potentially do something more hostile. This has been     resolved in Flatpak 1.12.3 and 1.10.6 by changing the behaviour of `--nofilesystem=home` and     `--nofilesystem=host`. (CVE-2022-21682)

As a workaround, use a GUI like GNOME     Software rather than the command-line interface, or only install apps whose maintainers you trust.
    (CVE-2023-28101)

  - 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 these issues but has instead relied only on the application's self-reported version number.

The remote Fedora 37 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2023-b0717d8c45 advisory.
