It was discovered that Puppet incorrectly handled filebucket retrieval
requests. A local attacker could exploit this to read arbitrary files.
(CVE-2012-1986)

local attacker could exploit this to perform a denial of service via resource

attacker could exploit this to execute arbitrary code via a crafted file path.
(CVE-2012-1988)
