"It was discovered that the Django Python web development framework did
not correct identify HTTP connections when a reverse proxy connected
via HTTPS.

When deployed behind a reverse-proxy connecting to Django via HTTPS
django.http.HttpRequest.scheme would incorrectly detect client
requests made via HTTP as using HTTPS. This resulted in incorrect
results for is_secure(), and build_absolute_uri(), and that HTTP
requests would not be redirected to HTTPS in accordance with
SECURE_SSL_REDIRECT.

HttpRequest.scheme now respects SECURE_PROXY_SSL_HEADER, if it is
configured, and the appropriate header is set on the request, for both
HTTP and HTTPS requests.

If you deploy Django behind a reverse-proxy that forwards HTTP
requests, and that connects to Django via HTTPS, be sure to verify
that your application correctly handles code paths relying on scheme,
is_secure(), build_absolute_uri(), and SECURE_SSL_REDIRECT.

For Debian 8 'Jessie', this issue has been fixed in python-django
version 1.7.11-1+deb8u6.

We recommend that you upgrade your python-django packages.

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."
