Debian LTS Advisory DLA-2569-1 [email protected]
https://www.debian.org/lts/security/ Chris Lamb
February 19, 2021 https://wiki.debian.org/LTS

Package : python-django
Version : 1:1.10.7-2+deb9u11
CVE ID : CVE-2021-23336
Debian Bug : #983090

It was discovered that there was a web cache poisoning attack in
Django, a popular Python-based web development framework.

This was caused by the unsafe handling of ";" characters in Python's
urllib.parse.parse_qsl method which had been backported to Django's
codebase to fix some other security issues in the past.

For Debian 9 "Stretch", this problem has been fixed in version
1:1.10.7-2+deb9u11.

We recommend that you upgrade your python-django packages.

For the detailed security status of python-django please refer to
its security tracker page at:
https://security-tracker.debian.org/tracker/python-django

Further information about Debian LTS security advisories, how to apply
these updates to your system and frequently asked questions can be
