"The remote EulerOS host is missing multiple security updates.");
  script_set_attribute(attribute:"description", value:
"According to the versions of the python-pip packages installed, the EulerOS installation on the remote host is affected
by the following vulnerabilities :

    pip would treat console_scripts and gui_scripts as paths instead of file names without sanitizing the
    resolved absolute path to the installation directory, leading to entry points being installed outside the
    installation directory.(CVE-2026-8643)

    pip handles concatenated tar and ZIP files as ZIP files regardless of filename or whether a file is both a
    tar and ZIP file. This behavior could result in confusing installation behavior, such as installing
    'incorrect' files according to the filename of the archive. New behavior only proceeds with installation
    if the file identifies uniquely as a ZIP or tar archive, not as both.(CVE-2026-3219)

    Requests is a HTTP library. Prior to version 2.33.0, the `requests.utils.extract_zipped_paths()` utility
    function uses a predictable filename when extracting files from zip archives into the system temporary
    directory. If the target file already exists, it is reused without validation. A local attacker with write
    access to the temp directory could pre-create a malicious file that would be loaded in place of the
    legitimate one. Standard usage of the Requests library is not affected by this vulnerability. Only
    applications that call `extract_zipped_paths()` directly are impacted. Starting in version 2.33.0, the
    library extracts files to a non-deterministic location. If developers are unable to upgrade, they can set
    `TMPDIR` in their environment to a directory with restricted write access.(CVE-2026-25645)

    When pip is installing and extracting a maliciously crafted wheel archive, files may be extracted outside
    the installation directory. The path traversal is limited to prefixes of the installation directory, thus
    isn't able to inject or overwrite executable files in typical situations.(CVE-2026-1703)

    urllib3 is an HTTP client library for Python. From 1.23 to before 2.7.0, cross-origin redirects followed
    from the low-level API via ProxyManager.connection_from_url().urlopen(..., assert_same_host=False) still
    forward these sensitive headers. This vulnerability is fixed in 2.7.0.(CVE-2026-44431)

Tenable has extracted the preceding description block directly from the EulerOS python-pip security advisory.

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