"The version of python3 installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore,
affected by a vulnerability as referenced in the CVE-2024-4030 advisory.

  - On Windows a directory returned by tempfile.mkdtemp() would not always have permissions set to restrict
    reading and writing to the temporary directory by other users, instead usually inheriting the correct
    permissions from the default location. Alternate configurations or users without a profile directory may
    not have the intended permissions. If you're not using Windows or haven't changed the temporary directory
    location then you aren't affected by this vulnerability. On other platforms the returned directory is
    consistently readable and writable only by the current user. This issue was caused by Python not
    supporting Unix permissions on Windows. The fix adds support for Unix 700 for the mkdir function on
    Windows which is used by mkdtemp() to ensure the newly created directory has the proper permissions.
    (CVE-2024-4030)

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