glib@2.62.6 is vulnerable to CVE-2021-27218 and CVE-2021-27219

Upstream does not provide fixes for the 2.62.x series so we need to
backport ourselves.

I would rather switch to upstream-supported version (2.66.x or later)
as backporting patches does not appear sustainable for us, we already
have enough on our plate.

See:
- https://gitlab.gnome.org/GNOME/glib/-/merge_requests/1942 (CVE-2021-
27218)
- https://gitlab.gnome.org/GNOME/glib/-/merge_requests/1944 (CVE-2021-
27218)
- https://gitlab.gnome.org/GNOME/glib/-/issues/2319 (CVE-2021-27219)

Hi Léo,

Thanks for bringing this to our attention.

One does not follow from the other.  Besides upstream, there exist other
competent organizations (such as Debian, Red Hat, and Ubuntu) that
provide security support for their stable OS releases, and publish
backported fixes as part of that work.

As I wrote in another thread: I'll backport the fixes for CVE-2021-27218
and CVE-2021-27219 to our version of Glib, based on the backports
already published by Ubuntu for Glib 2.56.4 and 2.64.4.

     Regards,
       Mark
