"The remote openSUSE 15 host has a package installed that is affected by multiple vulnerabilities as referenced in the
openSUSE-SU-2023:0272-1 advisory.

  - CairoSVG is a Python (pypi) package. CairoSVG is an SVG converter based on Cairo. In CairoSVG before
    version 2.5.1, there is a regular expression denial of service (REDoS) vulnerability. When processing SVG
    files, the python package CairoSVG uses two regular expressions which are vulnerable to Regular Expression
    Denial of Service (REDoS). If an attacker provides a malicious SVG, it can make cairosvg get stuck
    processing the file for a very long time. This is fixed in version 2.5.1. See Referenced GitHub advisory
    for more information. (CVE-2021-21236)

  - CairoSVG is an SVG converter based on Cairo, a 2D graphics library. Prior to version 2.7.0, Cairo can send
    requests to external hosts when processing SVG files. A malicious actor could send a specially crafted SVG
    file that allows them to perform a server-side request forgery or denial of service. Version 2.7.0
    disables CairoSVG's ability to access other files online by default. (CVE-2023-27586)

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