28th September, 2011
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 11.04
- Ubuntu 10.10
- Ubuntu 10.04 LTS
An attacker could send crafted input to puppet and cause it to overwrite files.

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:
- Ubuntu 11.04:
- puppet-common 2.6.4-2ubuntu2.2
- Ubuntu 10.10:
- puppet-common 2.6.1-0ubuntu2.1
- Ubuntu 10.04 LTS:
- puppet-common 0.25.4-2ubuntu6.2
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.
