  script_set_attribute(attribute:"description", value:
"The version of AHV installed on the remote host is prior to 10.3.0.1. It is, therefore, affected by multiple
vulnerabilities as referenced in the NXSA-AHV-10.3.0.1 advisory.

  - inftrees.c in zlib 1.2.8 might allow context-dependent attackers to have unspecified impact by leveraging
    improper pointer arithmetic. (CVE-2016-9840)

  - Sudo before 1.9.17p1, when used with a sudoers file that specifies a host that is neither the current host
    nor ALL, allows listed users to execute commands on unintended machines. (CVE-2025-32462)

  - Allows modifying some file metadata (e.g. last modified) with filter=data or file permissions (chmod)
    with filter=tar of files outside the extraction directory. You are affected by this vulnerability if
    using the tarfile module to extract untrusted tar archives using TarFile.extractall() or TarFile.extract()
    using the filter= parameter with a value of data or tar. See the tarfile extraction filters
    documentation https://docs.python.org/3/library/tarfile.html#tarfile-extraction-filter for more
    information. Only Python versions 3.12 or later are affected by these vulnerabilities, earlier versions
    don't include the extraction filter feature. Note that for Python 3.14 or later the default value of
    filter= changed from no filtering to `data, so if you are relying on this new default behavior then
    your usage is also affected. Note that none of these vulnerabilities significantly affect the installation
    of source distributions which are tar archives as source distributions already allow arbitrary code
    execution during the build process. However when evaluating source distributions it's important to avoid
    installing source distributions with suspicious links. (CVE-2024-12718)

  - Allows the extraction filter to be ignored, allowing symlink targets to point outside the destination
    directory, and the modification of some file metadata. You are affected by this vulnerability if using the
    tarfile module to extract untrusted tar archives using TarFile.extractall() or TarFile.extract() using the
    filter= parameter with a value of data or tar. See the tarfile extraction filters documentation
    https://docs.python.org/3/library/tarfile.html#tarfile-extraction-filter for more information. Note that
    for Python 3.14 or later the default value of filter= changed from no filtering to `data, so if you
    are relying on this new default behavior then your usage is also affected. Note that none of these
    vulnerabilities significantly affect the installation of source distributions which are tar archives as
    source distributions already allow arbitrary code execution during the build process. However when
    evaluating source distributions it's important to avoid installing source distributions with suspicious
    links. (CVE-2025-4138, CVE-2025-4330)

  - When using a TarFile.errorlevel = 0 and extracting with a filter the documented behavior is that any
    filtered members would be skipped and not extracted. However the actual behavior of TarFile.errorlevel = 0
    in affected versions is that the member would still be extracted and not skipped. (CVE-2025-4435)

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