CVE-2014-0481

The default configuration for the file upload handling system in Django before 1.4.14, 1.5.x before 1.5.9, 1.6.x before 1.6.6, and 1.7 before release candidate 3 uses a sequential file name generation process when a file with a conflicting name is uploaded, which allows remote attackers to cause a denial of service (CPU consumption) by unloading a multiple files with the same name.

Updated python-django and python-django14 packages fix security vulnerabilities:

These releases address an issue with reverse() generating external URLs (CVE-2014-0480); a denial of service involving file uploads (CVE-2014-0481); a potential session hijacking issue in the remote-user middleware (CVE-2014-0482); and a data leak in the administrative interface (CVE-2014-0483).

python-django was updated to 1.5.10 fixing bugs and security issues:

* Prevented reverse() from generating URLs pointing to other hosts to
  prevent phishing attacks. (bnc#893087, CVE-2014-0480)
* Removed O(n) algorithm when uploading duplicate file names to fix
  file upload denial of service. (bnc#893088, CVE-2014-0481)
* Modified RemoteUserMiddleware to logout on REMOTE_USE change to
  prevent session hijacking. (bnc#893089, CVE-2014-0482)
* Prevented data leakage in contrib.admin via query string
  manipulation. (bnc#893090, CVE-2014-0483)

Florian Apolloner discovered that Django incorrectly validated URLs. A remote attacker could use this issue to conduct phishing attacks. (CVE-2014-0480)

David Wilson discovered that Django incorrectly handled file name generation. A remote attacker could use this issue to cause Django to consume resources, resulting in a denial of service. (CVE-2014-0481)

David Greisen discovered that Django incorrectly handled certain headers in contrib.auth.middleware.RemoteUserMiddleware. A remote authenticated user could use this issue to hijack web sessions. (CVE-2014-0482)

Collin Anderson discovered that Django incorrectly checked if a field represented a relationship between models in the administrative interface. A remote authenticated user could use this issue to possibly obtain sensitive information. (CVE-2014-0483)
