Detail

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

- Ubuntu 14.10 - Ubuntu 14.04 LTS

Summary:

cgmanager could be made to expose sensitive information or devices to containers running on the system.

Software Description: - cgmanager: Central cgroup manager daemon

Details:

Serge Hallyn discovered that cgmanager did not consistently enforce proper nesting when modifying cgroup properties. A local attacker in a privileged container could use this to set cgroup values for all cgroups.

Update instructions:

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

Ubuntu 14.10:
cgmanager 0.32-4ubuntu1.1

Ubuntu 14.04 LTS:
cgmanager 0.24-0ubuntu7.1

After a standard system update you need to reboot your computer to make all the necessary changes.
