"The remote Debian 10 host has packages installed that are affected by a vulnerability as referenced in the dla-3470
advisory.

  - OWSLib is a Python package for client programming with Open Geospatial Consortium (OGC) web service
    interface standards, and their related content models. OWSLib's XML parser (which supports both `lxml` and
    `xml.etree`) does not disable entity resolution, and could lead to arbitrary file reads from an attacker-
    controlled XML payload. This affects all XML parsing in the codebase. This issue has been addressed in
    version 0.28.1. All users are advised to upgrade. The only known workaround is to patch the library
    manually. See `GHSA-8h9c-r582-mggc` for details. (CVE-2023-27476)

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