Fedora 29: 2018-009a65a873 Critical: Flatpak Permissions Issue

flatpak is a system for building, distributing and running sandboxed desktop

applications on Linux. See https://wiki.gnome.org/Projects/SandboxedApps for

more information.

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.
