Description Robert Frohl 2021-11-18 10:18:57 UTC
CVE-2021-3939

Ubuntu-specific modifications to accountsservice (in patch file
debian/patches/0010-set-language.patch) caused the fallback_locale variable,
pointing to static storage, to be freed, in the
user_change_language_authorized_cb function. This is reachable via the
SetLanguage dbus function. This is fixed in versions 0.6.55-0ubuntu12~20.04.5,
0.6.55-0ubuntu13.3, 0.6.55-0ubuntu14.1.
