Ubuntu Security Notice USN-1928-1
15th August, 2013
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.
- 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.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 13.04:
- puppet-common 2.7.18-4ubuntu1.2
- Ubuntu 12.10:
- puppet-common 2.7.18-1ubuntu1.3
- Ubuntu 12.04 LTS:
- puppet-common 2.7.11-1ubuntu2.4
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
In general, a standard system update will make all the necessary changes.
