"It was discovered that Puppet did not drop privileges when executing
commands as different users. If an attacker had control of the
execution manifests or the executed command, this could be used to
execute code with elevated group permissions (typically root).
(CVE-2012-1053)

It was discovered that Puppet unsafely opened files when the k5login
type is used to manage files. A local attacker could exploit this to
overwrite arbitrary files and escalate privileges. (CVE-2012-1054).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
