Notes
[wheezy] - systemd <not-affected> (Vulnerable code not present)
https://bugzilla.suse.com/show_bug.cgi?id=972612
Introduced by: https://github.com/systemd/systemd/commit/a606871da508995f5ede113a8fc6538afd98966c (v213)
Fixed by (for current persistent journal): https://github.com/systemd/systemd/commit/afae249efa4774c6676738ac5de6aeb4daf4889f (v229)
Starting with 215 Debian no longer ships tmpfiles.d/systemd.conf, so the fixup upstream added as
afae249efa4774c6676738ac5de6aeb4daf4889f for persistent journals is not needed for the packaged
version. Anyone using a custom config needs to ensure proper permissions.
