How to fix?

There is no fixed version for Debian:9 ncurses.

NVD Description

Note: Versions mentioned in the description apply only to the upstream ncurses package and not the ncurses package as distributed by Debian. See How to fix? for Debian:9 relevant fixed versions and status.

In ncurses 6.1, there is a NULL pointer dereference at function _nc_parse_entry in parse_entry.c that will lead to a denial of service attack. The product proceeds to the dereference code path even after a "dubious character `*' in name or alias field" detection.
