More information:

Several vulnerabilities were discovered in Django, a high-level Python web development framework. The Common Vulnerabilities and Exposures project identifies the following problems:

• CVE-2016-9013

  Marti Raudsepp reported that a user with a hardcoded password is created when running tests with an Oracle database.

• CVE-2016-9014

  Aymeric Augustin discovered that Django does not properly validate the Host header against settings.ALLOWED_HOSTS when the debug setting is enabled. A remote attacker can take advantage of this flaw to perform DNS rebinding attacks.

• CVE-2017-7233

  It was discovered that is_safe_url() does not properly handle certain numeric URLs as safe. A remote attacker can take advantage of this flaw to perform XSS attacks or to use a Django server as an open redirect.

• CVE-2017-7234

  Phithon from Chaitin Tech discovered an open redirect vulnerability in the django.views.static.serve() view. Note that this view is not intended for production use.

For the stable distribution (jessie), these problems have been fixed in version 1.7.11-1+deb8u2.

We recommend that you upgrade your python-django packages.
