Summary

ncurses security update

Details

The ncurses (new curses) library is a free software emulation of curses in System V Release 4.0 (SVr4), and more. It uses terminfo format, supports pads and color and multiple highlights and forms characters and function-key mapping, and has all the other SVr4-curses enhancements over BSD curses. SVr4 curses became the basis of X/Open Curses.

Security Fix(es):

The infocmp command-line tool in ncurses before 6.5-20251213 has a stack-based buffer overflow in analyze_string in progs/infocmp.c.(CVE-2025-69720)

Severity

7.8 (High)
