Insight
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.
