========================================================================== Ubuntu Security Notice USN-4951-1 May 12, 2021
flatpak vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 20.10 - Ubuntu 20.04 LTS - Ubuntu 18.04 LTS
Summary:
A Flatpak application could access files that it would not normally be permitted to access.
Software Description: - flatpak: Application deployment framework for desktop apps
Details:
Anton Lydike discovered that Flatpak did not properly handle special tokens in desktop files. An attacker could use this to specially craft a Flatpak application that could escape sandbox confinement.
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 20.10: flatpak 1.8.2-1ubuntu0.2 libflatpak0 1.8.2-1ubuntu0.2
Ubuntu 20.04 LTS: flatpak 1.6.5-0ubuntu0.3 libflatpak0 1.6.5-0ubuntu0.3
Ubuntu 18.04 LTS: flatpak 1.0.9-0ubuntu0.3 libflatpak0 1.0.9-0ubuntu0.3
In general, a standard system update will make all the necessary changes.
