Ubuntu 10.04 LTS / 10.10 / 11.04 / 11.10 : python-django vulnerabilities (USN-1297-1)

Ubuntu Security Notice (C) 2011-2016 Canonical, Inc. / NASL script (C) 2011-2016 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing a security-related patch.

Description :

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).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

Solution :

Update the affected python-django package.

Risk factor :

Medium / CVSS Base Score : 5.8

CVSS Temporal Score : 4.8
