affected by multiple vulnerabilities as referenced in the USN-6099-1 advisory.

  - There is a heap-based buffer over-read in the _nc_find_entry function in tinfo/comp_hash.c in the terminfo
    library in ncurses before 6.1-20191012. (CVE-2019-17594)

  - There is a heap-based buffer over-read in the fmt_entry function in tinfo/comp_hash.c in the terminfo
    library in ncurses before 6.1-20191012. (CVE-2019-17595)

  - An issue was discovered in ncurses through v6.2-1. _nc_captoinfo in captoinfo.c has a heap-based buffer
    overflow. (CVE-2021-39537)

  - ncurses 6.3 before patch 20220416 has an out-of-bounds read and segmentation violation in convert_strings
    in tinfo/read_entry.c in the terminfo library. (CVE-2022-29458)

  - ncurses before 6.4 20230408, when used by a setuid application, allows local users to trigger security-
    relevant memory corruption via malformed data in a terminfo database file that is found in $HOME/.terminfo
    or reached via the TERMINFO or TERM environment variable. (CVE-2023-29491)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
