CVE-2011-3872

Status Candidate

Overview

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."

Ubuntu Security Notice USN-1238-2
Posted Oct 25, 2011
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 1238-2 - USN-1238-1 fixed vulnerabilities in Puppet. The upstream patch introduced a regression in Ubuntu 11.04 when executing certain commands. This update fixes the problem. It was discovered that Puppet incorrectly handled the non-default "certdnsnames" option when generating certificates. If this setting was added to puppet.conf, the puppet master's DNS alt names were added to the X.509 Subject Alternative Name field of all certificates, not just the puppet master's certificate. An attacker that has an incorrect agent certificate in his possession can use it to impersonate the puppet master in a man-in-the-middle attack.
