"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

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues.");
