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
use this issue to cause a denial of service or to expose sensitive
information. (CVE-2019-17594)
It was discovered that ncurses was incorrectly handling
end-of-string characters when processing terminfo and termcap files.
An attacker could possibly use this issue to cause a denial of
service or to expose sensitive information. (CVE-2019-17595)
It was discovered that ncurses was incorrectly handling
end-of-string characters when converting between termcap and
terminfo formats. An attacker could possibly use this issue to cause
a denial of service or execute arbitrary code. (CVE-2021-39537)
It was discovered that ncurses was incorrectly performing bounds
checks when dealing with corrupt terminfo data while reading a
