EulerOS Virtualization for ARM 64 3.0.6.0 : python-lxml (EulerOS-SA-2021-1538)

medium Nessus Plugin ID 147095

Synopsis

The remote EulerOS Virtualization for ARM 64 host is missing multiple security updates.

Description

According to the versions of the python-lxml package installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

 - An issue was discovered in lxml before 4.2.5.
 lxml/html/clean.py in the lxml.html.clean module does not remove javascript: URLs that use escaping, allowing a remote attacker to conduct XSS attacks, as demonstrated by 'j a v a s c r i p t:' in Internet Explorer. This is a similar issue to CVE-2014-3146.(CVE-2018-19787)

 - A XSS vulnerability was discovered in python-lxml's clean module. The module's parser didn't properly imitate browsers, which caused different behaviors between the sanitizer and the user's page. A remote attacker could exploit this flaw to run arbitrary HTML/JS code.CVE-2020-27783)

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.
