python-django vulnerabilities

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

  • Ubuntu 10.10
  • Ubuntu 10.04 LTS
  • Ubuntu 9.10


Attackers could use Django to perform web-based attacks.

Software Description

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


It was discovered that Django did not properly validate HTTP requests that contain an X-Requested-With header. An attacker could exploit this vulnerability to perform cross-site request forgery (CSRF) attacks. (CVE-2011-0696)

It was discovered that Django did not properly sanitize its input when performing file uploads, resulting in cross-site scripting (XSS) vulnerabilities. With cross-site scripting vulnerabilities, if a user were tricked into viewing server output during a crafted server request, a remote attacker could exploit this to modify the contents, or steal confidential data, within the same domain. (CVE-2011-0697)

Update instructions

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

Ubuntu 10.10
python-django - 1.2.3-1ubuntu0.
Ubuntu 10.04 LTS
python-django - 1.1.1-2ubuntu1.3
Ubuntu 9.10
python-django - 1.1.1-1ubuntu1.2

To update your system, please follow these instructions:

ATTENTION: This update introduces a small backwards-imcompatible change to perform full CSRF validation on all requests. Prior to this update, AJAX requests were excepted from CSRF protections. For more details, please see

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