Summary:

Several security issues were fixed in Django.

Software Description:

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)
