Synopsis
========

Multiple vulnerabilities have been found in Django, the worst of which
may allow a remote attacker to cause Denial of Service.

Background
==========

Django is a Python-based web framework.

Affected packages
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  dev-python/django            < 1.8.3                    >= 1.8.3
                                                            *>= 1.7.9
                                                           *>= 1.4.21

Description
===========

Multiple vulnerabilities have been found in Django:

* Session backends create a new record anytime request.session was
  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)

Impact
======

A remote attacker may be able cause a Denial of Service condition,
inject arbitrary headers, and conduct HTTP response splitting attacks.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Django 1.8 users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=dev-python/django-1.8.3"

All Django 1.7 users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=dev-python/django-1.7.9"

All Django 1.4 users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=dev-python/django-1.4.21"
