- An issue was discovered in ncurses through v6.2-1. _nc_captoinfo in captoinfo.c has a heap-based buffer overflow. (CVE-2021-39537)

- ncurses before 6.4 20230408, when used by a setuid application, allows local users to trigger security- relevant memory corruption via malformed data in a terminfo database file that is found in $HOME/.terminfo or reached via the TERMINFO or TERM environment variable. (CVE-2023-29491)
