HIGH

Flatpak < 0.8.9 and 0.9.x-0.10.x < 0.10.3 - Sandbox Escape via D-Bus Message Whitespace Handling

STIX 2.1

Description

In dbus-proxy/flatpak-proxy.c in Flatpak before 0.8.9, and 0.9.x and 0.10.x before 0.10.3, crafted D-Bus messages to the host can be used to break out of the sandbox, because whitespace handling in the proxy is not identical to whitespace handling in the daemon.
