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-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)

  - In ncurses, possibly a 6.x version, there is a NULL pointer dereference at the function _nc_name_match     that will lead to a denial of service attack. NOTE: the original report stated version 6.1, but the issue     did not reproduce for that version according to the maintainer or a reliable third-party (CVE-2018-19217)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Ubuntu 16.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5477-1 advisory.

    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 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 terminfo file. An attacker could possibly use this issue to cause a denial of service     or to expose sensitive information. (CVE-2022-29458)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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