"It was discovered that Puppet used a predictable filename when
downloading Mac OS X package files. A local attacker could exploit
this to overwrite arbitrary files. (CVE-2012-1906)

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

It was discovered that Puppet incorrectly handled filebucket store
requests. A local attacker could exploit this to perform a denial of
service via resource exhaustion. (CVE-2012-1987)

It was discovered that Puppet incorrectly handled filebucket requests.
A local attacker could exploit this to execute arbitrary code via a
crafted file path. (CVE-2012-1988)

It was discovered that Puppet used a predictable filename for the
Telnet connection log file. A local attacker could exploit this to
overwrite arbitrary files. This issue only affected Ubuntu 11.10.
(CVE-2012-1989).

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."
