Original advisory details:

 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)");
