    Package : python-django
    CVE ID : CVE-2015-0219 CVE-2015-0220 CVE-2015-0221
    Debian Bug : 775375

    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.
