Detail

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

- Ubuntu 14.10 - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS

Summary:

USN-2431-1 caused a regression in the MAAS package.

Software Description: - maas: Ubuntu MAAS Server

Details:

USN-2431-1 fixed vulnerabilities in mod_wsgi. The security update exposed an issue in the MAAS package, causing a regression. This update fixes the problem.

We apologize for the inconvenience.

Original advisory details:

It was discovered that mod_wsgi incorrectly handled errors when setting up
the working directory and group access rights. A malicious application
could possibly use this issue to cause a local privilege escalation when
using daemon mode.

Update instructions:

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

Ubuntu 14.10:
maas-region-controller-min 1.7.0~beta8+bzr3272-0ubuntu1.2

Ubuntu 14.04 LTS:
maas-region-controller-min 1.5.4+bzr2294-0ubuntu1.2

Ubuntu 12.04 LTS:
maas-region-controller 1.2+bzr1373+dfsg-0ubuntu1~12.04.6

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