SecurityTracker URL:  http://securitytracker.com/id/1027324
CVE Reference:   CVE-2012-3442, CVE-2012-3443, CVE-2012-3444   (Links to External Site)
Date:  Jul 31 2012
Impact:   Denial of service via network, Disclosure of authentication information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): prior to versions 1.3.2 and 1.4.1
Description:   Several vulnerabilities were reported in Django. A remote user can cause denial of service conditions. A remote user can conduct cross-site scripting attacks.

The login() and logout() views do not properly filter HTML code from user-supplied input before displaying the input [CVE-2012-3442]. A remote user can cause arbitrary scripting code to be executed by the target user's browser. The code will originate from the site running the Django software and will run in the security context of that site. As a result, the code will be able to access the target user's cookies (including authentication cookies), if any, associated with the site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.

A remote user can create a specially crafted image file that, when validated by the target application, will consume excessive memory on the target system [CVE-2012-3443].

A remote user can create a specially crafted image file that, when processed by the target application, will trigger a flaw in get_image_dimensions() and consume excessive processing resources on the target system [CVE-2012-3444].

Impact:   A remote user can consume excessive memory or processing resources on the target system.

A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the Django software, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.

Solution:   The vendor has issued a fix (1.3.2, 1.4.1).

The vendor's advisory is available at:
