14 DAY TRIAL // In a security notice, Canonical published details about a Puppet regression in its Ubuntu 13.10, Ubuntu 13.04, Ubuntu 12.10, and Ubuntu 12.04 LTS operating systems.
According to the company, the USN-2077-1 security update introduced a regression in Puppet.
It has been discovered that USN-2077-1 fixed a vulnerability in Puppet, but the upstream patch introduced a regression resulting in the default file mode being incorrect. This update fixes the problem.
For a more detailed description of the problems, you can see Canonical's security notification.
The security flaws can be fixed if you upgrade your system(s) to the latest puppet-common package specific to each distribution. To apply the update, run the Update Manager application.
In general, a standard system update will make all the necessary changes, but this time a system restart will be necessary to implement them.
