NVD Description

Note: Versions mentioned in the description apply only to the upstream ncurses-base package and not the ncurses-base 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 an attempted 0xffffffffffffffff access in the append_acs 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.
