SuSE 11.1 Security Update : puppet (SAT Patch Number 5421)

medium Nessus Plugin ID 57129

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.
0.5 for detailed instructions and scripts.

- Directory traversal vulnerability in puppet allowed unauthenticated remote attackers to upload x.509 certificate signing requests to arbitrary locations.
(CVE-2011-3848)

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

Solution
