Package : python-django
Vulnerability : several

Debian-specific: no
CVE Id(s) : CVE-2008-3909 CVE-2007-5712
Debian Bug : 497765 448838

Simon Willison discovered that in Django, a Python web framework, the
feature to retain HTTP POST data during user reauthentication allowed
a remote attacker to perform unauthorized modification of data through
cross site request forgery. The is possible regardless of the Django
plugin to prevent cross site request forgery being enabled. The Common
Vulnerabilities and Exposures project identifies this issue as
CVE-2008-3909.

In this update the affected feature is disabled; this is in accordance
with upstream's preferred solution for this situation.

This update takes the opportunity to also include a relatively minor
denial of service attack in the internationalisaton framework, known
as CVE-2007-5712.

For the stable distribution (etch), these problems have been fixed in
version 0.95.1-1etch2.

For the unstable distribution (sid), these problems have been fixed in
version 1.0-1.

We recommend that you upgrade your python-django package.
