Description:	Summary: The remote host is missing an update for the 'flatpak, libostree, xdg-desktop-portal, xdg-desktop-portal-gtk' package(s) announced via the SUSE-SU-2021:1094-1 advisory. Vulnerability Insight: This update for flatpak, libostree, xdg-desktop-portal, xdg-desktop-portal-gtk fixes the following issues: libostree: Update to version 2020.8 Enable LTO. (bsc#1133120) This update contains scalability improvements and bugfixes. Caching-related HTTP headers are now supported on summaries and signatures, so that they do not have to be re-downloaded if not changed in the meanwhile. Summaries and delta have been reworked to allow more fine-grained fetching. Fixes several bugs related to atomic variables, HTTP timeouts, and 32-bit architectures. Static deltas can now be signed to more easily support offline verification. There's now support for multiple initramfs images, Is it possible to have a 'main' initramfs image and a secondary one which represents local configuration. The documentation is now moved to [link moved to references] Fix for an assertion failure when upgrading from systems before ostree supported devicetree. ostree no longer hardlinks zero sized files to avoid hitting filesystem maximum link counts. ostree now supports `/` and `/boot` being on the same filesystem. Improvements to the GObject Introspection metadata, some (cosmetic) static analyzer fixes, a fix for the immutable bit on s390x, dropping a deprecated bit in the systemd unit file. Fix a regression 2020.4 where the 'readonly sysroot' changes incorrectly left the sysroot read-only on systems that started out with a read-only `/` (most of them, e.g. Fedora Silverblue/IoT at least). The default dracut config now enables reproducibility. There is a new ostree admin unlock `--transient`. This should to be a foundation for further support for 'live' updates. New `ed25519` signing support, powered by `libsodium`. stree commit gained a new `--base` argument, which significantly simplifies constructing 'derived' commits, particularly for systems using SELinux. Handling of the read-only sysroot was reimplemented to run in the initramfs and be more reliable. Enabling the `readonly=true` flag in the repo config is recommended. Several fixes in locking for the temporary 'staging' directories OSTree creates, particularly on NFS. A new `timestamp-check-from-rev` option was added for pulls, which makes downgrade protection more reliable and will be used by Fedora CoreOS. Several fixes and enhancements made for 'collection' pulls including a new `--mirror` option. The ostree commit command learned a new `--mode-ro-executables` which enforces `W^R` semantics on all executables. Added a new commit metadata key `OSTREE_COMMIT_META_KEY_ARCHITECTURE` to help standardize the architecture of the OSTree commit. This could be used on the client side for example to sanity-check that the commit matches the architecture of the machine before deploying. Stop invalid usage of `%_libexecdir`: + Use `%{_prefix}/lib` where appropriate. + Use `_systemdgeneratordir` for ...
