puppet vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 13.04
  • Ubuntu 12.10
  • Ubuntu 12.04 LTS


Several security issues were fixed in Puppet.

Software Description

  • puppet - Centralized configuration management


It was discovered that Puppet incorrectly handled the resource_type service. A local attacker on the master could use this issue to execute arbitrary Ruby files. (CVE-2013-4761)

It was discovered that Puppet incorrectly handled permissions on the modules it installed. Modules could be installed with the permissions that existed when they were built, possibly exposing them to a local attacker. (CVE-2013-4956)
