How to fix?

Upgrade Debian:8 ncurses to version 5.9+20140913-1+deb8u1 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:8 relevant fixed versions and status.

In ncurses 6.0, there is a format string vulnerability in the fmt_entry function. A crafted input will lead to a remote arbitrary code execution attack.
