Ubuntu alert USN-1297-1 (python-django)
========================================================================== Ubuntu Security Notice USN-1297-1 December 09, 2011 python-django vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 11.10 - Ubuntu 11.04 - Ubuntu 10.10 - Ubuntu 10.04 LTS Summary: Applications using Django could be made to crash or expose sensitive information. Software Description: - python-django: High-level Python web development framework Details: Pall McMillan discovered that Django used the root namespace when storing cached session data. A remote attacker could exploit this to modify sessions. (CVE-2011-4136) Paul McMillan discovered that Django would not timeout on arbitrary URLs when the application used URLFields. This could be exploited by a remote attacker to cause a denial of service via resource exhaustion. (CVE-2011-4137) Paul McMillan discovered that while Django would check the validity of a URL via a HEAD request, it would instead use a GET request for the target of a redirect. This could potentially be used to trigger arbitrary GET requests via a crafted Location header. (CVE-2011-4138) It was discovered that Django would sometimes use a request's HTTP Host header to construct a full URL. A remote attacker could exploit this to conduct host header cache poisoning attacks via a crafted request. (CVE-2011-4139) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 11.10: python-django 1.3-2ubuntu1.1 Ubuntu 11.04: python-django 1.2.5-1ubuntu1.1 Ubuntu 10.10: python-django 1.2.3-1ubuntu0.2.10.10.3 Ubuntu 10.04 LTS: python-django 1.1.1-2ubuntu1.4 In general, a standard system update will make all the necessary changes.
