Description Nikos Mavrogiannopoulos 2017-05-09 09:45:38 UTC

Description of problem:
Internationalized domain names exist for quite some time (IDNA2003), although the protocols describing them have evolved in an incompatible way (IDNA2008). These incompatibilities will prevent applications written for IDNA2003 to access certain problematic domain names defined with IDNA2008, e.g., faß.de is translated to domain xn--fa-hia.de with IDNA2008, while in IDNA2003 it is translated to fass.de domain. That not only causes incompatibility problems, but may be used as an attack vector to redirect users to different web sites.

The change is about deprecating libidn, which supports IDNA2003, and switch all applications using libidn, to libidn2 2.0.0, which supports IDNA2008. The switch should be transparent as the libidn2 library is API compatible. See instructions at:
https://libidn.gitlab.io/libidn2/manual/libidn2.html#Converting-from-libidn


This is part of the IDNA2008 change:

If upstream is not aware of that change please involve them on the process.

Hi Petr,
 I'm reporting this issue to the maintainers of the packages on the distribution. If you think this package has no maintainer please let me know. I do not want to get in touch with all the upstreams involved, though I am available to answer any questions if required.

Comment 3 Petr Špaček 2017-05-30 15:36:23 UTC

Ah, my bad. I've updated this bug instead of the 'blocking' one. Sorry for the noise.

Comment 4 Jan Kurik 2017-08-15 07:42:46 UTC

This bug appears to have been reported against 'rawhide' during the Fedora 27 development cycle.
Changing version to '27'.

Comment 5 Nikos Mavrogiannopoulos 2017-11-23 08:32:15 UTC

Hi Paul,
 Has this been addressed or forwarded to upstream?

Comment 6 Nicki Křížek 2018-01-22 13:06:54 UTC

This has been fixed since 2.5.3-1
