April 22, 2014

Several security issues were fixed in Django.

Summary

Several security issues were fixed in Django.

Software Description:

- python-django: High-level Python web development framework

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)
