Kristian Erik Hermansen discovered a directory traversal vulnerability in
the SSLFile indirection base class. A remote attacker could exploit this to
overwrite files with the privileges of the Puppet Master.
The problem can be corrected by updating your system to the following package version:

To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
In general, a standard system update will make all the necessary changes.
