NVD Description

Note: Versions mentioned in the description apply only to the upstream ncurses package and not the ncurses package as distributed by Amazon-Linux. See How to fix? for Amazon-Linux:2 relevant fixed versions and status.

In ncurses 6.0, there is a stack-based buffer overflow in the fmt_entry function. A crafted input will lead to a remote arbitrary code execution attack.
