Description:Multiple file overwrite vulnerabilities, certificates spooging.
Affected:PUPPET : Puppet 2.6
CVE:CVE-2011-3872 (Puppet 2.6.x before 2.6.12 and 2.7.x before 2.7.6, and Puppet Enterprise (PE) Users 1.0, 1.1, and 1.2 before 1.2.4, when signing an agent certificate, adds the Puppet master's certdnsnames values to the X.509 Subject Alternative Name field of the certificate, which allows remote attackers to spoof a Puppet master via a man-in-the-middle (MITM) attack against an agent that uses an alternate DNS name for the master, aka "AltNames Vulnerability.")
 CVE-2011-3871 (Puppet 2.7.x before 2.7.5, 2.6.x before 2.6.11, and 0.25.x, when running in --edit mode, uses a predictable file name, which allows local users to run arbitrary Puppet code or trick a user into editing arbitrary files.)
 CVE-2011-3870 (Puppet 2.7.x before 2.7.5, 2.6.x before 2.6.11, and 0.25.x allows local users to modify the permissions of arbitrary files via a symlink attack on the SSH authorized_keys file.)
 CVE-2011-3869 (Puppet 2.7.x before 2.7.5, 2.6.x before 2.6.11, and 0.25.x allows local users to overwrite arbitrary files via a symlink attack on the .k5login file.)
