"value": "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."

"value": "Flatpak es un sistema para crear, distribuir y ejecutar aplicaciones de escritorio en espacio aislado en Linux. en versiones anteriores a la 1.10.9, 1.12.9, 1.14.6 y 1.15.8, una aplicaci\u00f3n Flatpak maliciosa o comprometida podr\u00eda ejecutar c\u00f3digo arbitrario fuera de su zona de pruebas. Normalmente, el argumento `--command` de `flatpak run` espera recibir un comando para ejecutar en la aplicaci\u00f3n Flatpak especificada, opcionalmente junto con algunos argumentos. Sin embargo, es posible pasar argumentos `bwrap` a `--command=`, como `--bind`. Es posible pasar una \"l\u00ednea de comando\" arbitraria a la interfaz del portal \"org.freedesktop.portal.Background.RequestBackground\" desde una aplicaci\u00f3n Flatpak. Cuando esto se convierte en un `--command` y argumentos, logra el mismo efecto de pasar argumentos directamente a `bwrap` y, por lo tanto, puede usarse para un escape sandbox. La soluci\u00f3n es pasar el argumento `--` a `bwrap`, lo que hace que deje de procesar las opciones. Esto ha sido compatible desde bubblewrap 0.3.0. Todas las versiones compatibles de Flatpak requieren al menos esa versi\u00f3n de bubblewrap. xdg-desktop-portal versi\u00f3n 1.18.4 mitigar\u00e1 esta vulnerabilidad al permitir que las aplicaciones Flatpak solo creen archivos .desktop para comandos que no comiencen con --. La vulnerabilidad est\u00e1 parcheada en 1.15.8, 1.10.9, 1.12.9 y 1.14.6."
