NVD Description

Note: Versions mentioned in the description apply only to the upstream emacs-libidn package and not the emacs-libidn package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

The idna_to_ascii_4i function in lib/idna.c in libidn before 1.33 allows context-dependent attackers to cause a denial of service (out-of-bounds read and crash) via 64 bytes of input.
