According to the versions of the ncurses packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

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

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The version of ncurses installed on the remote host is prior to 6.0-8.20170212. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2022-1893 advisory.

    The ncurses package (tic) is susceptible to a heap overflow on crafted input. When the terminfo entry-     description compiler processes input, proper bounds checking was not enforced leading to this software     flaw. The highest threat from this vulnerability is system availability. (CVE-2021-39537)

    A segmentation fault vulnerability was found in ncurses's convert_strings() function of tinfo/read_entry.c     file. This flaw occurs due to corrupted terminfo data, triggering an out-of-bounds read error.
    (CVE-2022-29458)

The remote Ubuntu 16.04 ESM / 18.04 LTS / 20.04 LTS / 22.04 LTS / 23.04 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6099-1 advisory.

    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.
    This issue only affected Ubuntu 18.04 LTS. (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. This issue only affected Ubuntu 18.04 LTS. (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. This issue only affected Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. (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. This issue only affected Ubuntu 18.04 LTS, Ubuntu 20.04 LTS and Ubuntu     22.04 LTS. (CVE-2022-29458)

    It was discovered that ncurses was parsing environment variables when running with setuid applications and     not properly handling the processing of malformed data when doing so.
