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.");

  script_tag(name:"vuldetect", value:"This check tests the installed software version using the apt package manager.");
