Description

Django is a high-level Python Web framework that encourages rapid development and a clean, pragmatic design. It focuses on automating as much as possible and adhering to the DRY (Don't Repeat Yourself) principle.

The following packages have been upgraded to a later upstream version: python-django (1.8.18). (BZ#1437737)

Security Fix(es):

• A redirect flaw, where the is_safe_url() function did not correctly sanitize numeric-URL user input, was found in python-django. A remote attacker could exploit this flaw to perform XSS attacks against the OpenStack dashboard. (CVE-2017-7233)
