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. For the oldstable distribution (lenny), this problem has been fixed in version 1.0.2-1+lenny3. For the stable distribution (squeeze), this problem has been fixed in version 1.2.3-3+squeeze2. For the testing (wheezy) and unstable distribution (sid), this problem has been fixed in version 1.3.1-1. We recommend that you upgrade your python-django packages.
