openSUSE Security Update : puppet (openSUSE-SU-2011:1288-1)

medium Nessus Plugin ID 75999

Language:

Synopsis

The remote openSUSE host is missing a security update.

Description

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-cve20113872-0.0.5 for detailed instructions and scripts.

Puppet was prone to several symlink attacks (CVE-2011-3870, CVE-2011-3869, CVE-2011-3871)

Solution
