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