Package        : python-django
CVE ID         : CVE-2016-9013 CVE-2016-9014 CVE-2017-7233 CVE-2017-7234
Debian Bug     : 842856 859515 859516

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.
