Debian Security Advisory DSA-3010-1 security ( -at -) debian.org

Package : python-django

CVE ID : CVE-2014-0480 CVE-2014-0481 CVE-2014-0482 CVE-2014-0483

 

Several vulnerabilities were discovered in Django, a high-level Python

web development framework. The Common Vulnerabilities and Exposures

project identifies the following problems:

 

CVE-2014-0480

 

Florian Apolloner discovered that in certain situations, URL

reversing could generate scheme-relative URLs which could

unexpectedly redirect a user to a different host, leading to

phishing attacks.

 

CVE-2014-0481

 

David Wilson reported a file upload denial of service vulnerability.

Django's file upload handling in its default configuration may

degrade to producing a huge number of `os.stat()` system calls when

a duplicate filename is uploaded. A remote attacker with the ability

to upload files can cause poor performance in the upload handler,

eventually causing it to become very slow.

 

CVE-2014-0482

 

David Greisen discovered that under some circumstances, the use of

the RemoteUserMiddleware middleware and the RemoteUserBackend

authentication backend could result in one user receiving another

user's session, if a change to the REMOTE_USER header occurred

without corresponding logout/login actions.

 

CVE-2014-0483

 

Collin Anderson discovered that it is possible to reveal any field's

data by modifying the "popup" and "to_field" parameters of the query

string on an admin change form page. A user with access to the admin

interface, and with sufficient knowledge of model structure and the

appropriate URLs, could construct popup views which would display

the values of non-relationship fields, including fields the

application developer had not intended to expose in such a fashion.

 

For the stable distribution (wheezy), these problems have been fixed in

version 1.4.5-1+deb7u8.

 

For the unstable distribution (sid), these problems have been fixed in

version 1.6.6-1.

 

We recommend that you upgrade your python-django packages.
