More information:

It was discovered that there were two vulnerabilities in python-django, a high-level Python web development framework.

  • CVE-2017-7233 (#859515)

    Open redirect and possible XSS attack via user-supplied numeric redirect URLs. Django relies on user input in some cases (e.g. django.contrib.auth.views.login() and i18n) to redirect the user to an on success URL. The security check for these redirects (namely is_safe_url()) considered some numeric URLs (e.g. http:999999999) safe when they shouldn't be. Also, if a developer relied on is_safe_url() to provide safe redirect targets and puts such a URL into a link, they could suffer from an XSS attack.

  • CVE-2017-7234 (#895516)

    Open redirect vulnerability in django.views.static.serve; A maliciously crafted URL to a Django site using the serve() view could redirect to any other domain. The view no longer does any redirects as they don't provide any known, useful functionality.

For Debian 7 Wheezy, this issue has been fixed in python-django version 1.4.22-1+deb7u3.

We recommend that you upgrade your python-django packages.
