The utils.http.is_safe_url function in Django before 1.8.10 and 1.9.x before 1.9.3 allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks or possibly conduct cross-site scripting (XSS) attacks via a URL containing basic authentication, as demonstrated by http://mysite.example.com\@attacker.com.

Affected: Ubuntu:14.04:LTS: python-django

Mark Striemer discovered that Django incorrectly handled user-supplied redirect URLs containing basic authentication credentials. A remote attacker could possibly use this issue to perform a cross-site scripting attack or a malicious redirect. (CVE-2016-2512)

Sjoerd Job Postmus discovered that Django incorrectly handled timing when doing password hashing operations. A remote attacker could possibly use this issue to perform user enumeration. (CVE-2016-2513)
