		<Note Title="Summary" Type="General" Ordinal="2" xml:lang="en">An update for python-lxml is now available for openEuler-20.03-LTS-SP1 and openEuler-20.03-LTS-SP2 and openEuler-20.03-LTS-SP3.</Note>
		<Note Title="Description" Type="General" Ordinal="3" xml:lang="en">XML processing library combining libxml2/libxslt with the ElementTree API.

Security Fix(es):

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>
		<Note Title="Topic" Type="General" Ordinal="4" xml:lang="en">An update for python-lxml is now available for openEuler-20.03-LTS-SP1 and openEuler-20.03-LTS-SP2 and openEuler-20.03-LTS-SP3.

openEuler Security has rated this update as having a security impact of high. A Common Vunlnerability Scoring System(CVSS)base score,which gives a detailed severity rating, is available for each vulnerability from the CVElink(s) in the References section.</Note>
