"flatpak 1.0.5 release.

There was a sandbox bug in the previous version where parts of the
runtime /etc was not mounted read-only. In case the runtime was
installed as the user (not the default) this means that the app could
modify files on the runtime. Nothing in the host uses the runtime
files, so this is not a direct sandbox escape, but it is possible that
an app can confuse a different app that has higher permissions and so
gain privileges.

Detailed changes :

  - Make the /etc -> /usr/etc bind-mounts read-only.

  - Make various app-specific configuration files read-only.

  - flatpak is more picky about remote names to avoid
    problems with storing weird names in the ostree config.

  - A segfault in libflatpak handling of bundles was fixed.

  - Updated translations

  - Fixed a regression in flatpak run that caused problems
    running user-installed apps when the system installation
    was broken.

In addition to upstream changes, this update also fixes a packaging
issue and adds a missing dependency on p11-kit-server to fix accessing
host TLS certificates.

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as
possible without introducing additional issues."
