Summary:
Several security issues were fixed in puppet.
Software Description:

Details:
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)
