How to fix?

Upgrade Debian:9 ncurses to version 6.0+20161126-1+deb9u1 or higher.

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, possibly a 6.x version, there is a NULL pointer dereference at the function _nc_name_match that will lead to a denial of service attack. NOTE: the original report stated version 6.1, but the issue did not reproduce for that version according to the maintainer or a reliable third-party
