Details

Benjamin Bach discovered that Django incorrectly handled dotted Python
paths when using the reverse() function. An attacker could use this issue
to cause Django to import arbitrary modules from the Python path, resulting
in possible code execution. (CVE-2014-0472)

Paul McMillan discovered that Django incorrectly cached certain pages that
contained CSRF cookies. An attacker could possibly use this flaw to obtain
a valid cookie and perform attacks which bypass the CSRF restrictions.
(CVE-2014-0473)

Michael Koziarski discovered that Django did not always perform explicit
conversion of certain fields when using a MySQL database. An attacker
could possibly use this issue to obtain unexpected results. (CVE-2014-0474)
