USN-1066-1: Django vulnerabilities

Releases

• Ubuntu 10.10
• Ubuntu 10.04
• Ubuntu 9.10

Packages

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

Details

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 9.10

• python-django - 1.1.1-1ubuntu1.2

Ubuntu 10.10

• python-django - 1.2.3-1ubuntu0.2.10.10.2

Ubuntu 10.04

• python-django - 1.1.1-2ubuntu1.3

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 http://docs.djangoproject.com/en/1.2/releases/1.2.5/.

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