Hi Kevin, those 4 security issues were fixed via DSA-3798-1 in jessie-security, by backporting the appropriate upstream changes (thanks to Thorsten for doing that).
I've verified 1.4.13 only contains those security fixes, and no new major evolution or feature, so could you please prepare and upload it to unstable ? The Security Team would then be able to ask for an unblock so those problems also end up fixed in stretch. Cheers, --Seb
