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

The remote Redhat Enterprise Linux 8 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - ncurses: Heap buffer overflow in _nc_find_entry in tinfo/comp_hash.c:70 (CVE-2020-19190)

  - ncurses: heap-based buffer overflow in _nc_captoinfo() in captoinfo.c (CVE-2021-39537)

  - 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. (CVE-2018-19211)
