Releases

• Ubuntu 14.10
• Ubuntu 14.04 ESM
• Ubuntu 12.04

Packages

• 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

• maas-region-controller-min - 1.5.4+bzr2294-0ubuntu1.2

Ubuntu 12.04

• maas-region-controller - 1.2+bzr1373+dfsg-0ubuntu1~12.04.6

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