A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 14.04 LTS - Ubuntu 13.10 - Ubuntu 12.10 - Ubuntu 12.04 LTS - Ubuntu 10.04 LTS

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)

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 14.04 LTS:
python-django 1.6.1-2ubuntu0.1

Ubuntu 13.10:
python-django 1.5.4-1ubuntu1.1

Ubuntu 12.10:
python-django 1.4.1-2ubuntu0.5

Ubuntu 12.04 LTS:
python-django 1.3.1-4ubuntu1.9

Ubuntu 10.04 LTS:

In general, a standard system update will make all the necessary changes.
