Package : lxml
Version : 3.7.1-1+deb9u5
CVE ID : CVE-2021-43818
Debian Bug : 1001885
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.
For Debian 9 stretch, this problem has been fixed in version
3.7.1-1+deb9u5.
We recommend that you upgrade your lxml packages.
