EulerOS 2.0 SP5 : python-lxml (EulerOS-SA-2020-2296)

medium Nessus Plugin ID 142071

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

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

 - Incomplete blacklist vulnerability in the lxml.html.clean module in lxml before 3.3.5 allows remote attackers to conduct cross-site scripting (XSS) attacks via control characters in the link scheme to the clean_html function.(CVE-2014-3146)

 - 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)

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.
