Package        : python-django
CVE ID         : CVE-2015-5963 CVE-2015-5964

Lin Hua Cheng discovered that a session could be created when anonymously
accessing the django.contrib.auth.views.logout view. This could allow
remote attackers to saturate the session store or cause other users'
session records to be evicted.

Additionally the contrib.sessions.backends.base.SessionBase.flush() and
cache_db.SessionStore.flush() methods have been modified to avoid
creating a new empty session as well.

For the oldstable distribution (wheezy), these problems have been fixed
in version 1.4.5-1+deb7u13.

For the stable distribution (jessie), these problems have been fixed in
version 1.7.7-1+deb8u2.

For the unstable distribution (sid), these problems will be fixed
shortly.

We recommend that you upgrade your python-django packages.
