Comment 5 Michael Catanzaro 2022-12-27 14:32:02 UTC

Note this vulnerability was only present in gvdb for six days, and no version of glib or dconf is affected, so users don't need to worry about this. I believe Epiphany is the only software that was actually impacted (and it was fixed there before it made its way into any release).
