may allow a remote attacker to cause Denial of Service.

Background
=========

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------

Description

  accessed (CVE-2015-5143)
* Built-in validators in Django do not properly sanitize input
  (CVE-2015-5144)
* URL validation included a regular expression that was extremely slow
  (CVE-2015-5145)
