    Several vulnerabilities were discovered in Django, a high-level Python
    web development framework. The Common Vulnerabilities and Exposures
    project identifies the following problems:
    
    CVE-2015-0219
    
        Jedediah Smith reported that the WSGI environ in Django does not
        distinguish between headers containing dashes and headers containing
        underscores. A remote attacker could use this flaw to spoof WSGI
        headers.
    
    CVE-2015-0220
    
        Mikko Ohtamaa discovered that the django.util.http.is_safe_url()
        function in Django does not properly handle leading whitespaces in
        user-supplied redirect URLs. A remote attacker could potentially use
        this flaw to perform a cross-site scripting attack.
    
    CVE-2015-0221
    
        Alex Gaynor reported a flaw in the way Django handles reading files
        in the django.views.static.serve() view. A remote attacker could
        possibly use this flaw to mount a denial of service via resource
        consumption.
    
    For the stable distribution (wheezy), these problems have been fixed in
    version 1.4.5-1+deb7u9.
    
    For the upcoming stable distribution (jessie), these problems have been
    fixed in version 1.7.1-1.1.
    
    For the unstable distribution (sid), these problems have been fixed in
    version 1.7.1-1.1.
    
    We recommend that you upgrade your python-django packages.
