Notes

mdeslaur

upstream patch switched from libidn to libidn2 and may be causing issues, see: https://curl.haxx.se/mail/lib-2016-11/0033.html http://seclists.org/oss-sec/2016/q4/333 Fixing this is intrusive and is likely to cause regressions in stable releases. As such, we will not be fixing this issue in Ubuntu 16.04 LTS and earlier.
