Debian Security Advisory DSA-4880-1 security@debian.org
https://www.debian.org/security/ Sebastien Delafond
March 29, 2021 https://www.debian.org/security/faq
- - -------------------------------------------------------------------------
Package : lxml
CVE ID : CVE-2021-28957
Debian Bug : 985643
Kevin Chung discovered that lxml, a Python binding for the libxml2 and
libxslt libraries, did not properly sanitize its input. This would
allow a malicious user to mount a cross-site scripting attack.
For the stable distribution (buster), this problem has been fixed in
version 4.3.2-1+deb10u3.
We recommend that you upgrade your lxml packages.
For the detailed security status of lxml please refer to
its security tracker page at:
https://security-tracker.debian.org/tracker/lxml
