This update for flatpak fixes the following issues:
CVE-2021-21381: Fixed an issue where a sandboxed application could
read and write arbitrary host files via special tokens in the
.desktop file (bsc#1183459).
CVE-2021-21261: Fixed a sandbox escape issue via the flatpak-portal
service (bsc#1180996).
Non-security fixes:
openh264 extension needs to use 'extradata'. (bsc#1155688)
The update will provide the support for extradata' in extensions
and will provide a list of versions that are supported. This will
be useful for the extradata for extensions because that will require
it to say that it is supported for version > 1.2.5 in the 1.2 series
and > 1.4.2 otherwise.
The update will includes fixes for a segfault in the function that
lists the installed references (flatpakinstallationlistinstalled_refs).
When an appstream update is cancelled while downloading icons, the update
will show a proper fail. Before this fix the next update attempt will see
an up-to-date timestamp, think everyhing is ok and not download the missing icons.
The update will introduce checks in the OCI (Open Container Initiative format)
updates for validating if it is gpg verified.
The update will install the required runtime for the installed extension.
The update will prevent a crash if the 'FlatpakDir' can't ensure it has a repo configured.
The update will prevent the removal of local extensions considered remote and not locally related.
