USN-2741-1: Unity Settings Daemon vulnerability

Releases

• Ubuntu 15.04
• Ubuntu 14.04 ESM

Packages

• unity-settings-daemon - daemon handling the Unity session settings

Details

It was discovered that the Unity Settings Daemon incorrectly allowed
removable media to be mounted when the screen is locked. If a vulnerability
were discovered in some other desktop component, such as an image library,
a local attacker could possibly use this issue to gain access to the
session.

Update instructions

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

Ubuntu 15.04

• unity-settings-daemon - 15.04.1+15.04.20150408-0ubuntu1.2

Ubuntu 14.04

• unity-settings-daemon - 14.04.0+14.04.20150825-0ubuntu2

After a standard system update you need to restart your session to make
all the necessary changes.
