I just noticed that you are listing CVE-2015-5479 and CVE-2015-1872 as still open for 0.8 on https://security-tracker.debian.org/tracker/CVE-2015-5479 https://security-tracker.debian.org/tracker/CVE-2015-1872 We fixed this a long time ago with release 0.8.18, you can mark these as fixed for wheezy and close the CVE entries.
