python-django - security update

Several vulnerabilities were discovered in Django, a high-level Python
web development framework. The Common Vulnerabilities and Exposures
project identifies the following problems:

• CVE-2014-0480
  Florian Apolloner discovered that in certain situations, URL
  reversing could generate scheme-relative URLs which could
  unexpectedly redirect a user to a different host, leading to
  phishing attacks.
• CVE-2014-0481
  David Wilson reported a file upload denial of service vulnerability.
  Django’s file upload handling in its default configuration may
  degrade to producing a huge number of os.stat() system calls when
  a duplicate filename is uploaded. A remote attacker with the ability
  to upload files can cause poor performance in the upload handler,
  eventually causing it to become very slow.
• CVE-2014-0482
  David Greisen discovered that under some circumstances, the use of
  the RemoteUserMiddleware middleware and the RemoteUserBackend
  authentication backend could result in one user receiving another
  user’s session, if a change to the REMOTE_USER header occurred
  without corresponding logout/login actions.
• CVE-2014-0483
  Collin Anderson discovered that it is possible to reveal any field’s
  data by modifying the popup and to_field parameters of the query
  string on an admin change form page. A user with access to the admin
  interface, and with sufficient knowledge of model structure and the
  appropriate URLs, could construct popup views which would display
  the values of non-relationship fields, including fields the
  application developer had not intended to expose in such a fashion.

For the stable distribution (wheezy), these problems have been fixed in
version 1.4.5-1+deb7u8.

For the unstable distribution (sid), these problems have been fixed in
version 1.6.6-1.

We recommend that you upgrade your python-django packages.
