high Nessus Plugin ID 159980

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the versions of the python-lxml package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

- 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. Users that employ the HTML cleaner in a security relevant context should upgrade to lxml 4.6.5 to receive a patch. There are no known workarounds available. (CVE-2021-43818)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected python-lxml packages.
