SuSE 11.1 Security Update : puppet (SAT Patch Number 5421)
medium Nessus Plugin ID 57129
Language:
Synopsis
The remote SuSE 11 host is missing one or more security updates.Description
The following security issues have been fixed :- Puppet's certificate authority issued Puppet agent certificates capable of impersonating the Puppet master.
Compromised or rogue puppet agents could therefore use their certificates for MITM attacks. (CVE-2011-3872)
Note: If you've set the 'certdnsnames' option in your master's puppet.conf file merely installing the updated packages is not sufficient to fix this problem. You need to either pick a new DNS name for the master and reconfigure all agents to use it or re-new certificates on all agents.
Please refer to the documentation in /usr/share/doc/packages/puppet/puppetlabs-cve20113872-0.
