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.

Update instructions

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

Ubuntu 13.10
Ubuntu 13.04
Ubuntu 12.10
Ubuntu 12.04

In general, a standard system update will make all the necessary changes.
