Overview

puppet is an automated configuration management tool. Affected versions of the package are vulnerable to Symlink Attack via a user's .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.

The .k5login file previously wrote to the target file directly, as root, without doing anything to secure the file. If the .k5login file was replaced with a symlink, this would allow the owner of the home directory to replace any file on the system, including the .k5login file of a more privileged user, with the “correct” content of their own file.
