How to fix?

There is no fixed version for Centos:7 libidn.

NVD Description

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

The stringprep_utf8_nfkc_normalize function in lib/nfkc.c in libidn before 1.33 allows context-dependent attackers to cause a denial of service (out-of-bounds read and crash) via crafted UTF-8 data.
