CVE-2017-16879 [HIGH] ncurses vulnerabilities
Title: ncurses vulnerabilities
Summary: Several security issues were fixed in ncurses.
Hosein Askari discovered that ncurses was incorrectly performing
memory management operations when dealing with long filenames while
writing structures into the file system. An attacker could possibly
use this issue to cause a denial of service or execute arbitrary
code. (CVE-2017-16879)
Chung-Yi Lin discovered that ncurses was incorrectly handling access
to invalid memory areas when parsing terminfo or termcap entries where
the use-name had invalid syntax. An attacker could possibly use this
issue to cause a denial of service. (CVE-2018-19211)
It was discovered that ncurses was incorrectly performing bounds
checks when processing invalid hashcodes. An attacker could possibly

ncurses: Null pointer dereference at function _nc_parse_entry in parse_entry.c
In ncurses 6.1, there is a NULL pointer dereference at function _nc_parse_entry in parse_entry.c that will lead to a denial of service attack. The product proceeds to the dereference code path even after a "dubious character `*' in name or alias field" detection.
A vulnerability was found in GNU ncurses due to a NULL pointer dereference in the _nc_parse_entry function within parse_entry.c, where an attacker could exploit this flaw by persuading a victim to open a specially crafted file, leading to a crash and causing a denial of service condition.
Statement: This vulnerability was rated as LOW severity because it requires the victim to open a specially crafted file. While it doesn’t allow full system compromi
