The last release of libidn, 1.33, fixed this bugs:
https://security-tracker.debian.org/tracker/CVE-2015-8948
https://security-tracker.debian.org/tracker/CVE-2016-6261
https://security-tracker.debian.org/tracker/CVE-2016-6263
We already have libidn 1.33 on core-updates.
Quoted from the release announcment [0]:
** libidn: Fix out-of-bounds stack read in idna_to_ascii_4i.
See tests/tst_toascii64oob.c for regression check (and the comment in
it how to use it). Reported by Hanno Böck <address@hidden>.
** idn: Solve out-of-bounds-read when reading one zero byte as input.
Also replaced fgets with getline. Reported by Hanno Böck <address@hidden>.
** libidn: stringprep_utf8_nfkc_normalize reject invalid UTF-8.
It was always documented to only accept UTF-8 data, but now it doesn't
crash when presented with such data. Reported by Hanno Böck.
** Dropped valgrind suppressions file, should no longer be needed.
** API and ABI is backwards compatible with the previous version.
