    Several vulnerabilities have been discovered in python-django, a high-level
    python web development framework.  The Common Vulnerabilities and
    Exposures project identifies the following problems:
    
    
    CVE-2012-4520
    
        James Kettle discovered that django did not properly filter the HTTP
        Host header when processing certain requests. An attacker could exploit
        this to generate and cause parts of django, particularly the
        password-reset mechanism, to display arbitrary URLs to users.
    
    CVE-2013-0305
    
        Orange Tsai discovered that the bundled administrative interface
        of django could expose supposedly-hidden information via its history
        log.
    
    CVE-2013-0306
    
        Mozilla discovered that an attacker can abuse django's tracking of
        the number of forms in a formset to cause a denial-of-service attack
        due to extreme memory consumption.
    
    CVE-2013-1665
    
        Michael Koziarski discovered that django's XML deserialization is
        vulnerable to entity-expansion and external-entity/DTD attacks.
    
    For the stable distribution (squeeze), these problems have been fixed in
    version 1.2.3-3+squeeze5.
    
    For the testing distribution (wheezy), these problems will be fixed soon.
    
    For the unstable distribution (sid), these problems have been fixed in
    version 1.4.4-1.
    
    We recommend that you upgrade your python-django packages.
