Notes

[jessie] - policycoreutils <not-affected> ("sandbox" executable not packaged in this version)
https://bugzilla.redhat.com/show_bug.cgi?id=1378577
Upstream mailing list discussion: https://marc.info/?t=147463464400001&r=1&w=2
Upstream fix: https://github.com/SELinuxProject/selinux/commit/acca96a135a4d2a028ba9b636886af99c0915379
Marked as exception as not-affected, although the source is affected but the built
binary packages do not contain the sandbox binary. We cannot use 'unimportant'
severity here since the unstable version builts a binary package which contains it.
