Description of problem: The following was reported today to the public (Sept, 2, 2008) via the Django main site:

The Django administration application, as a convenience for users whose sessions expire, will attempt to preserve HTTP POST data from an incoming submission while re-authenticating the user, and will -- on successful authentication -- allow the submission to continue without requiring data to be re-entered.

Django developer Simon Willison has presented the Django development team with a proof-of-concept cross-site request forgery (CSRF) which exploits this behavior to perform unrequested deletion/modification of data. This exploit has been tested and verified by the Django team, and succeeds regardless of whether Django's bundled CSRF-protection module is active.

Version-Release number of selected component (if applicable): Django-0.96.2-1

Extra Info Since I am not aware if the maintainer of the package was given advance notice I'm cc'ing him on this bug.

The internationalization (i18n) framework in Django 0.91, 0.95, 0.95.1, and 0.96, and as used in other products such as PyLucid, when the USEI18N option and the i18n component are enabled, allows remote attackers to cause a denial of service (memory consumption) via many HTTP requests with large Accept-Language headers.
