Summary

The remote host is missing an update for the 'python-django' package(s) announced via the DSA-1842-1 advisory.

Insight

Insight

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.
