python-lxml-3.2.1-4.0.1.el7.AXS7

lxml provides a Python binding to the libxslt and libxml2 libraries. It follows
the ElementTree API as much as possible in order to provide a more Pythonic
interface to libxml2 and libxslt than the default bindings. In particular, lxml
deals with Python Unicode strings rather than encoded UTF-8 and handles memory
management automatically, unlike the default bindings.

Security Fix(es):

* CVE-2021-43818: prevent certain crafted script content passing through in HTML
Cleaner

CVE(s):
CVE-2021-43818
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.
