CVE-2023-28101 Information

Description

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.
