The ncurses (new curses) library routines are a terminal-independent method of updating character screens with reasonable optimization. The ncurses packages contain support utilities including a terminfo compiler tic, a decompiler infocmp, clear, tput, tset, and a termcap conversion tool captoinfo.

Security Fix(es):

  • ncurses: heap-based buffer overflow in the _nc_find_entry function in tinfo/comp_hash.c (CVE-2019-17594)

  • ncurses: heap-based buffer overflow in the fmt_entry function in tinfo/comp_hash.c (CVE-2019-17595)
