NVD Description

Note: Versions mentioned in the description apply only to the upstream puppet package and not the puppet package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

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."
