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 6.0, there is a NULL Pointer Dereference in the _nc_parse_entry function of tinfo/parse_entry.c. It could lead to a remote denial of service attack if the terminfo library code is used to process untrusted terminfo data.
