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

  • Ubuntu 13.10
  • Ubuntu 13.04
  • Ubuntu 12.10
  • Ubuntu 12.04 LTS

Summary

USN-2077-1 introduced a regression in Puppet.

Software Description

  • puppet - Centralized configuration management

Details

USN-2077-1 fixed a vulnerability in Puppet. The upstream patch introduced a regression resulting in the default file mode being incorrect. This update fixes the problem.

We apologize for the inconvenience.

Original advisory details:

It was discovered that Puppet incorrectly handled temporary files. A local attacker could possibly use this issue to overwrite arbitrary files. In the default installation of Ubuntu, this should be prevented by the Yama link restrictions.

The problem can be corrected by updating your system to the following package versions:

Ubuntu 13.10
puppet-common - 3.2.4-2ubuntu2.3

puppet-common - 2.7.18-4ubuntu1.4
Ubuntu 12.10
puppet-common - 2.7.18-1ubuntu1.5
Ubuntu 12.04 LTS
puppet-common - 2.7.11-1ubuntu2.7

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.
