Ubuntu Security Notice USN-1634-1
November 20, 2012

python-keyring vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.10
- Ubuntu 12.04 LTS
- Ubuntu 11.10

Summary:

Several security issues were fixed in Python Keyring.

Software Description:
- python-keyring: store and access your passwords safely

Details:

Dwayne Litzenberger discovered that Python Keyring's CryptedFileKeyring
file format used weak cryptography. A local attacker may use this issue to
brute-force CryptedFileKeyring keyring files. This issue only affected
Ubuntu 11.10 and Ubuntu 12.04 LTS. (CVE-2012-4571)

It was discovered that Python Keyring created keyring files with insecure
permissions. A local attacker could use this issue to access keyring files
belonging to other users.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 12.10:
python-keyring 0.9.2-1ubuntu0.2
python3-keyring 0.9.2-1ubuntu0.2

Ubuntu 12.04 LTS:
python-keyring 0.9.2-0ubuntu0.12.04.2
python3-keyring 0.9.2-0ubuntu0.12.04.2

Ubuntu 11.10:
python-keyring 0.9.2-0ubuntu0.11.10.2

In general, a standard system update will make all the necessary changes.
This update uses a new upstream release, which includes additional bug
fixes, and will migrate existing keyring files to the new format upon first
use.

Ubuntu Security Notice USN-1632-2

python-django regression
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.10
- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 10.04 LTS

Summary:

A testsuite regression was fixed in Django.

Software Description:
- python-django: High-level Python web development framework

Details:

USN-1632-1 fixed a vulnerability in Django. The upstream fix introduced
testsuite failures when ADMINS and/or MANAGERS were defined in settings.py.
This update fixes the problem.

We apologize for the inconvenience.

Original advisory details:

James Kettle discovered Django did not properly filter the Host HTTP header
when processing certain requests. An attacker could exploit this to
generate and display arbitrary URLs to users.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 12.10:
python-django 1.4.1-2ubuntu0.2

Ubuntu 12.04 LTS:
python-django 1.3.1-4ubuntu1.4

Ubuntu 11.10:
python-django 1.3-2ubuntu1.5

Ubuntu 10.04 LTS:
python-django 1.1.1-2ubuntu1.7

In general, a standard system update will make all the necessary changes.
