CVE-2017-16879

CVE-2017-16879 is a stack-based buffer overflow vulnerability in the _nc_write_entry function of ncurses 6.0, specifically impacting the tinfo/write_entry.c file. This flaw allows an attacker to trigger a denial of service or potentially execute arbitrary code by supplying a specially crafted terminfo file, as demonstrated through the tic utility. With a CVSS score of 7.8 (HIGH), it requires local access and user interaction (e.g., opening a malicious file) but can lead to high confidentiality, integrity, and availability impacts. Currently, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage, suggesting a low immediate threat.
