    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.
