[buster] - apparmor <ignored> (Minor overall security impact)
[stretch] - apparmor <ignored> (Minor overall security impact)
[jessie] - apparmor <ignored> (Minor overall security impact)
Introduced around AppArmor 2.8 upstream.
Mount rules support is enabled in Debian, but the impact of the issue is
limited to 1. lxc (not a regression, as Debian never confined LXC with AppArmor
by default before buster, in particular not with mount rules), 2. libvirtd
but the profile is not meant to be a strong security boundary.
