Description

The remote CentOS Linux 9 host has a package installed that is affected by a vulnerability as referenced in the python- lxml-4.6.5-1.el9 build changelog.

- lxml is a library for processing XML and HTML in the Python language. Prior to version 4.6.5, the HTML Cleaner in lxml.html lets certain crafted script content pass through, as well as script content in SVG files embedded using data URIs.
