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.
