Descriptions

Flatpak before 1.0.7, and 1.1.x and 1.2.x before 1.2.3, exposes /proc in the apply_extra script sandbox, which allows attackers to modify a host-side executable file.

Flatpak, en versiones anteriores a la 1.0.7 y en versiones 1.1.x y 1.2.x anteriores a la 1.2.3, expone /proc en el sandbox de script apply_extra, lo que permite que los atacantes modifiquen un archivo ejecutable del lado del host.

A flaw was found in flatpak. In certain special cases, installing flatpak applications and runtimes system-wide may allow an attacker to escape the flatpak sandbox. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
