Description Jan Lieskovsky 2011-09-29 06:10:33 EDT

A directory traversal flaw was found in the way SSLFile and YAML Puppet indirector base classes performed management or certain, user-supplied x509 certificate signing requests. An authenticated attacker could use this flaw to overwrite arbitrary system file, accessible with the privileges of the Puppet Master application.
