Alex Larsson is today announcing the availability of Flatpak 0.8.1, the first point release of the new stable series. This appears to be a bugfix and security update, marked as CVE-2017-5226, bundled with bubblewrap 0.1.7 to addresses a security vulnerability that would allow an attacker to inject text on the controlling TTY. Flatpak 0.8.1 re-implements the ability to update applications by installing newer bundles, a functionality that was apparently not working properly in previous versions of the app sandboxing and distribution framework, which was recently adopted by popular Solus operating system.
