Paul McMillan, Mozilla and the Django core team discovered several vulnerabilities in Django, a Python web framework :
CVE-2011-4136 When using memory-based sessions and caching, Django sessions are stored directly in the root namespace of the cache. When user data is stored in the same cache, a remote user may take over a session.
CVE-2011-4137, CVE-2011-4138 Django’s field type URLfield by default checks supplied URL’s by issuing a request to it, which doesn’t time out. A Denial of Service is possible by supplying specially prepared URL’s that keep the connection open indefinately or fill the Django’s server memory.
CVE-2011-4139 Django used X-Forwarded-Host headers to construct full URL’s. This header may not contain trusted input and could be used to poison the cache.
CVE-2011-4140 The CSRF protection mechanism in Django does not properly handle web-server configurations supporting arbitrary HTTP Host headers, which allows remote attackers to trigger unauthenticated forged requests.
