Upgrade puppet to version 2.6.14, 2.7.11 or higher.
Overview
puppet is an automated configuration management tool.
Affected versions of the package are vulnerable to Local User Privilege Escalation .k5login file. The k5login type is typically used to manage a file in the home directory of a user. The purpose of this file is to allow access to other users.
If a user's .k5login file was replaced with a symlink, Puppet will overwrite the link's target when managing that user's login file with the k5login resource type. This allows local privilege escalation by linking a user's .k5login file to root's .k5login file.
