Releases

• Ubuntu 12.10
• Ubuntu 12.04

Details

It was discovered that Puppet incorrectly handled the resource_type
service. A local attacker on the primary server 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.
